Classic Disney Shorts Looney Tunes Theatrical shorts from The Golden Age of Animation starring a venerable cast of Funny Animals. Overall, Disney cartoons were more sentimental, with a whimsical tone and picturesque animation meant to appeal to the viewers' inner child. Looney Tunes was a lot more raw, face-paced, and Fourth Wall Breaking in its animation and humor, meaning to appeal to the common man. Though both still have mostly equivalent fanbases, if a winner was to be chosen, it would probably be Disney because… well, other than just because, the Disney studios still exist and still produce shorts, while the original Warner Bros. cartoon studio is long dead.
Once Upon a Time...Man (1977) Meme: The Dream Journeys (1983) Make a show like (respectively) Bronowski's The Ascent of Man or Carl Sagan's Cosmos: A Personal Voyage, but specifically aimed at children Man is broody and even creepy in places, while Meme is distinctly Lighter and Softer in tone, much in line their grown-up predecessors. Man was shown all over the world right out of the starting gate, Meme took nearly a dozen years to be shown outside of its native Japan. Both were dubbed into English, but neither aired in the United States. Man was more wide-ranging in scope and seriously explored the dangers of nuclear war, Meme gets bonus points for effectively predicting the rise of the Internet.
Thomas (the Tank Engine) & Friends (1984) Magic Adventures of Mumfie (1994) Short stories told by a narrator who also voices the characters based on old British children's books that teach morals to preschoolers. Both series are produced by Britt Allcroft, but it's also important to know that the Mumfie books predated The Railway Series by ten years. They also appeared together on Fox Family and Nick Jr. UK at one point. Thomas & Friends wins, as it's a very successful franchise amongst the target demographic and is still on today. Mumfie, on the other hand, had beat Thomas in popularity for a year and a half when it was on Nick Jr. UK, but that all changed when Little Bill premiered. Needless to say, the show faded into obscurity, and you're more likely to find someone who watched the Pilot Movie of the show rather than the episodes it was made out of or the episodes that came after it. Wether Mumfie will pop out of obscurity and one again topple Thomas depends on how well the upcoming Zodiak Kids remake does.
Thomas (the Tank Engine) & Friends (1984) Chuggington (2008) Short stories about a fleet of anthropomorphic train engines and their daily working lives on the railway targeted at young children. The stories often contain An Aesop for the target audience to learn. Expect to hear lots of train-themed puns. Thomas & Friends was initially filmed using real railway models in live-action and the episodes were presented as if someone was reading them from a storybook; a storyteller would narrate the stories and do all the character voices. Later seasons use CGI models and gave each character their own voice actor (though the storyteller was still present). Chuggington used CGI models from the start and doesn't have a narrator; the episodes rely purely on dialogue. The characters in Chuggington are animated in a much more lively manner, showing lots of body language even if it defies the laws of physics, safety and engineering. The body language for the engines in Thomas & Friends is largely restricted to facial expressions. Most likely Thomas & Friends, because it has a much longer brand history than Chuggington. The latter is still being derided as being a ripoff of the former. The fact that Chuggington was created by former employees who worked on Thomas & Friends doesn't really help. Either way, it shouldn't matter since when it comes to the toys, Fisher-Price holds the rights to both franchises in the US, while Takara-Tomy holds the rights to both in Japan.
The Transformers (1984) Challenge of the GoBots (1984) Western-produced shows with Transforming Mecha. Challenge of the GoBots seems to be the obvious pale knockoff...so it comes as a surprise to many that the GoBots toys actually predated Transformers by two years. Nonetheless, the cartoon Autobots beat the Go Bots to TV by a month. Transformers became a Cash Cow Franchise that's still going strong some thirty years later. GoBots faded into obscurity and became a punchline on purpose, mainly because Hasbro ended up later buying GoBots's company and locked down the copyrights completely in order to keep "Transformers" in the public eye.
Filmation's Ghostbusters (1986) The Real Ghostbusters (1986) Cartoon adaptation of a live action TV series/Film about a team of detectives/geeks confronting ghosts and such. Both series premiered at the same year featuring Filmation and Columbia Pictures' long dispute for the copyrights of the name. The Real Ghostbusters, by the virtue that only animation geeks who were into really obscure shows would know and care what Filmation's Ghostbusters is.
Saber Rider and the Star Sheriffs (1987) Bravestarr (1987) and Adventures of the Galaxy Rangers (1986) Space Western Animated Series with Mechanical Horses. Saber Rider was the first of these shows; its original Japanese version, Sei Juushi Bismarck,note  aired in 1984. In America, Galaxy Rangers came first in 1986, with the other two shows following in 1987. Galaxy Rangers was Darker and Edgier than its competitorsnote  and seems to have the biggest fan following today, although none of the series did very well in America. Bravestarr is the best known of the three outside of the animation fandom, but Rangers is the most popular within that fandom.
Teenage Mutant Ninja Turtles (1987) Biker Mice from Mars (1993) & Street Sharks (1994) A group of mutated antropomorphic animals fight against a power-hungry madman and his incompetent lackeys. There were MANY TMNT imitators but Biker Mice from Mars and Street Sharks are among the most prominent. Ninja Turtles, no doubt. Street Sharks was actually decently popular during its time but it never got any continuation and is pretty much a joke today. Biker Mice from Mars received a second animated series in 2006 that's shares continuity with the 1993 series.
C.O.P.S. (1988) Robocop The Animated Series (1988) Both shows involve police who are (as C.O.P.S. put it) "fighting crime in a future time". Although the film that the latter show is based on predates the former series, the former series technically came first since it originally aired on weekdays. It's hard to say. Both shows have toylinesnote  that have a similar "cap firing" gimmick, plus Robocop was already established as a popular (albeit, R-rated) movie. In any event, Robocop tends to be talked more than the other show especially since mentioning a show called "Cops" tends have people think of that other show.note 
Denver the Last Dinosaur (1988) Dink, the Little Dinosaur (1989) Animated series about dinosaurs having adventures and a Green Aesop or two. Denver had a one-year head start, aired in syndication and was set in modern-day while Dink came a year later (inspired partly by The Land Before Time, released inbetween the two shows), was aired by CBS and took place in the Stone Age. Both shows ran two seasons but Denver the Last Dinosaur is more fondly remembered and had more episodes (50 vs. 21) than Dink.
Garfield and Friends (1988) Eek! The Cat (1992) Comedic multiple-segment Saturday Morning Cartoon about a wisecracking Fat Cat who lives with an annoying owner, has lots of misadventures, and dislikes dogs with a passion. Both cartoons have the same art design for some characters, and they even have a second segment that has very different characters,note  but Eek! The Cat seems a bit Darker and Edgier than Garfield and Friends. While both are very well-known and well-remembered, Garfield and Friends wins because it still exists today in other media (comic strips, books, toys, printed merchandise and a revival CGI cartoon series)
The Simpsons (1989) Family Guy (1999) Primetime animated series about a Dysfunctional Family with a moronic, brash jerk of a father, a patient and loving wife who sometimes has a mean streak, and three kids (a dimwitted son, a social outcast daughter, and a baby known for killing people). They also have a dog who is much more important to the latter show than the former. Dueling Shows made by the same network. While The Simpsons has been on the air longer, inspired the likes of Family Guy and other animated shows about dysfunctional and idiosyncratic families, and is loved/remembered/revered/quoted/written about/studied more, Family Guy has been kicking the show's butt in the ratings and does have a sizable fanbase (mostly made up of former Simpsons fans), thanks to its three-year cancellation and revival through DVD sales and cable reruns in the mid-2000s. Nevertheless, both shows are among the most popular and widely recognized cartoons of all times.
Captain Planet and the Planeteers (1990) Widget The World Watcher (1990) Saving the environment through use of superpowers.   Captain Planet is generally more remembered than Widget (despite that Captain Planet is often mocked for being preachy and politically correct, tried to do episodes about social issues such as AIDS, gang violence, and nuclear war, and not getting into any serious issues as to why pollution happens), so it wins.
Gravedale High (1990) Tiny Toon Adventures (1990) Cartoons taking place at a high school involving teenagers from a new generation based on classic characters from the Golden Age of Hollywood (movie monsters/theatrical cartoon characters). Gravedale High had teen-aged expies of Universal monsters and Rick Moranis as a human teacher, who happens to be the main character. Tiny Toons was a spin-off of the Looney Tunes (naturally) that not only had hijinks ensue, but would occasionally educate the viewers. Both shows have Frank Welker and Maurice LaMarche as regular cast members. Tiny Toons lasted for three seasons, is fondly remembered, and airs in syndication on The Hub/Discovery Family Channel while Gravedale lasted 13 episodes, isn't remembered by anyone besides the people who remember seeing the show, and isn't syndicated anywhere.
The Ren & Stimpy Show (1991) Rocko's Modern Life (1993) Surreal Nickelodeon cartoons with extremely wacky animation styles and disturbingly edgy styles of humor that skimmed toward older audiences Back in the 1990s, Ren & Stimpy revitalized the concept of deranged and dangerous animation that could be for both adults and kids, leading to many imitations of its style. Rocko's Modern Life was one such imitator that was dismissed as a rip-off with no redeeming value. Also, Ren & Stimpy focused more on creepy and gross humor, while Rocko focused more on wacky and zany humor. Both shows are fondly remembered and have very loyal fanbases. Rocko's Modern Life benefited from the fact that it didn't have the behind the scenes drama that plagued Ren & Stimpynote , nor did it have an excessively vulgar revival that was canceled as quickly as it premiered (cf. Ren & Stimpy's Adult Party Cartoon). However, Ren & Stimpy wins because it did, for better or worse, bring back the kind of edge and audacity in animation that hasn't been seen since The '60s, is a more recognizable franchise than Rocko, and animation fans and animators tend to copy Ren and Stimpy more than Rocko's Modern Life.
The Ren & Stimpy Show (1991) Cow and Chicken (1997) Kids' cartoons in The '90s that starred a Big Guy, Little Guy duo of Funny Animals, one shrimpy and temperamental, the other a heavyset Kindhearted Simpleton. Both shows greatly employed Deranged Animation, Gross Up Close Ups, and Getting Crap Past the Radar.   Like the above rivalry, Ren and Stimpy wins, with Cow and Chicken largely brushed off as one of Ren and Stimpy's many pale imitators. Ironically, Ren and Stimpy creator John Kricfalusi has said that he likes Cow and Chicken.
Batman: The Animated Series (1992) X-Men (1992) Comic Books adaptations that brought darker, more complex storylines to children's animation. In 1992, Comic Book rivals, DC and Marvel, in about of a month of each other, released a show based on one of their most popular licenses onto Fox Kids. Both became not only popular, but are noted as being the start of bringing darker and more complex stories to comic book programming, and children's programming in general. Both were very well received at the time and are considered staples of the comic book adaptation to this day, and both were about equally merchandised, as well as being both DC and Marvel's longest running animated series for a time. However, Batman: The Animated Series had 85 episodes to X-Men's 76, as well as two spin-offs (The New Batman Adventures and Batman Beyond) and two movies (Batman: Mask of the Phantasm and Batman & Mr. Freeze: Sub-Zero), which X-Men didn't have. Batman is also often cited as the greatest comic book adaptation of all time and some even go so far as to call it the greatest cartoon of all time, where as X-Men, though popular in its time and considered a good series in its own right, never gets that kind of praise.
Animaniacs (1993) The Wacky World of Tex Avery (1997) Collections of cartoon shorts in half-hour kid shows. Tex Avery is alleged to be an homage to old Tex Avery cartoons while Animaniacs is original itself, but has a lot of the classic Looney Tunes-style humor remade for the 1990s. Animaniacs by a long shot. It had great ratings, lasted for 6 years, was very positively reviewed, and is on DVD and in syndication on cable. The Wacky World of Tex Avery, on the other hand, is loathed by critics and viewers, only lasted a year before getting the ax, and hasn't been seen on TV since it premiered.
The Baby Huey Show (1994) The Twisted Tales of Felix the Cat (1995) A modern take on classic cartoon characters. The second season of Baby Huey was produced by Film Roman (the same company behind Twisted Tales of Felix). It's a tie. Both shows were good, but they didn't last long enough, though, if you did a YouTube search, you would find more episodes of Twisted Tales of Felix the Cat than The Baby Huey Show.
The Tick (1994) Freakazoid! (1995) Deconstructive Superhero parodies with completely insane main characters. The Tick had over a year head start and had stared in comics since the mid 80s. The Tick. Despite both being considered Cult Classic with loyal fan bases, The Tick ended up with one more season and a recent comic revival while Freakazoid! was Screwed by the Network and was canceled after just two seasons.
Gargoyles (1994) Mummies Alive! (1997) Ancient monsters awaken in the modern day. They Fight Crime. Gargoyles was a major departure from much of what was happening in western animation, with arcing story lines, an expansive mythology, and emphasis on character development. Mummies Alive! tried to mimic many of these elements, but was less than successful in doing so. Gargoyles got two seasons, a continuation series (Gargoyles: The Goliath Chronicles), and a comic book, as well as inspiring an annual convention that went on for a full twelve years after the show was canceled. Mummies Alive! only got one season, and while it garnered a small cult following, it didn't make nearly the impact that Gargoyles did.
What A Cartoon! Show (1995) Oh Yeah! Cartoons (1998) Animated Anthologies Cartoon Network's WACS and Nickelodeon's Oh Yeah both featured stand-alone shorts and recurring series. Several cartoons from both shows spun-off into full series (including Dexter's Laboratory, The Powerpuff Girls, Johnny Bravo, and Courage the Cowardly Dog in the former, and My Life as a Teenage Robot and The Fairly OddParents in the latter). They even shared one cartoon series: Mina and The Count, which debuted on WACS and moved to Oh Yeah. Both were developed by the same man, Fred Seibert. The jury's out on this one. Both shows went on to create some of the best modern classic cartoons. In this case, it all depends on which one you found to produce the better shows.
KaBlam! (1996) Oh Yeah! Cartoons (1998) Nickelodeon animated sketch comedies that presented about four shorts an episode. KaBlam! normally had the same shorts per episode, with a few one-shots in there to mix things up. Oh Yeah! featured different shorts every episode. Oh Yeah Cartoons got better treatment by Nickelodeon than Kablam! ever did and was the starting point for a few of Nickelodeon's standout franchises (see the entry v. What a Cartoon! Show above, but Kablam! has a dedicated fanbase to fall back on and spawned a couple of its own full-fledged series. Oh Yeah Cartoons wins by virtue of its spawn having a much larger impact than Kablam!'s, which consisted of the decent-but-forgettable Action League Now! and the generally-loathed Angela Anaconda.
Dexter's Laboratory (1996) The Adventures of Jimmy Neutron: Boy Genius (2002) Science Fiction cartoons in which a Child Prodigy uses his Improbably High I.Q. to invent all sorts of things to improve his life (with a tendency to backfire), travel through space, and battle evil. The lead of Dexter's Lab was characterized as a European Mad Scientist stuck in the role of a boy in a suburban Nuclear Family, the show being something of a Fish out of Water comedy of errors. Jimmy Neutron, however, was about a typical boy with a super-genius intellect who had a circle of friends and approached problems like a little boy would, acting as more of an adventurous Escapist Character. One thing both leads had in common is that for all their intelligence, they didn't have much in the way of common sense. Jimmy Neutron had a longer run than Dexter's Lab that improved in its later seasons whereas Dexter's Lab declined. However, Dexter's Lab is largely remembered more favorably than Jimmy Neutron, as its visuals have aged better, it never made any erroneous scientific claims, and Dexter is less of a Designated Hero than Jimmy.
Hey Arnold! (1996) Recess (1997) A group of fourth grade kids and their usual and unusual adventures with their friends Hey Arnold! didn't have school as its main focus (while a bunch of episodes focused on school, it wasn't the main point of the show), while Recess focuses more on the kids at school. While both are remembered fondly by those who grew up on 1990s cartoons, Recess wins, as it had a more successful movie than Hey Arnold! and had a longer run and more merchandising.
Recess (1997) Detention (1999) A group of kids have misadventures in school under the eye of a large strict female teacher. One Saturday Morning was beating Kids' WB! in the ratings race, so it seems pretty obvious here that Warner Bros. decided to Follow the Leader. Recess is the clear winner, having lasted six seasons and even landing a theatrical feature film. Detention was canceled after one season and isn't remembered much.
South Park (1997) The Boondocks (2005) Shows that satire certain current topics around plots of a community of idiots, while the children turn out to usually be the only ones with common sense. Both shows are cable cartoons that are much more obscene and satirical than The Simpsons, and often go after taboo and rarely-mocked social issues. While South Park goes after everything and anything that may be bothering Trey Parker and Matt Stone this week, The Boondocks tends to stick with issues about African-American culture and modern-day racial issues between white people and black people. While both are very well-known series, South Park is the clear winner. It's still on the air, still being praised for its humor (after being derided in its early days for being a vulgar grossout show), and its satire is sharper than ever. While The Boondocks had usually also been well-received, its fourth (and final) season got a lot of backlash due to its creator Aaron McGruder leaving the show.
Men in Black (1997) Roswell Conspiracies: Aliens, Myths and Legends (1999) Shows that feature an earth-based organization dedicated to protecting the planet from aliens. While Men In Black did have a recurring villain who featured into an overarcing plot, most episodes were a stand alone affair. Roswell however featured a very strong central myth arc as well as several other story arcs that all concluded in the final set of episodes. Men In Black lasted four seasons totaling 53 episodes while Roswell lasted only one 40 episode season. Men In Black was popular on the Kids WB block and is fondly remembered today. Sharing its name and characters with a film didn't hurt matters. Roswell aired on BKN, and as a result never got the attention Men In Black did.
CatDog (1998) The Fairly OddParents (2001) An egotictic Butt Monkey gets bullied by the people around him except is true friends. Both shows inderduce a new main character in later seasons. When Odd Parents does so, people hate the show for it. But when CatDog does so, it's the other way around. In addition, The voice of Eddie the Squirrel sound a lot like Dr. Bender. Fairly Odd Parents became Nick's second long running animated series and is still running on this very day. CatDog got Screwed by the Network and was cancelled due to Seasonal Rot. Plus Nick did squat to promote the third and final season.
The Powerpuff Girls (1998) Teamo Supremo (2002) A trio of children take time off from their schoolwork to fight crime. The big difference, though, was that the Powerpuff Girls were superpowered sisters born as the result of a lab accident. Teamo, on the other hand, were ¡Three Amigos! of no blood relation who instead used supertools. The Powerpuff Girls — it has a movie, an anime adaptation, a reboot, two anniversary specials, a complete series DVD set (including a lot of episodes that didn't air on TV), lots of merchandise, syndication on Cartoon Network's sister channel Boomerang, and more fans than Teamo Supremo could ever wish for. Teamo Supremo, on the other hand, only ran for about a year, and was then cancelled due to low ratings and complaints that it ripped off PPG.
Godzilla: The Series (1998) Alienators: Evolution Continues (2001) An animated series based off a movie in which scientists save the world from monsters. Godzilla had to balance the exploits of the human team with Godzilla's epic battles with other monsters. Of the two shows Alienators seems to have been geared towards a younger audience. Godzilla lasted for two seasons compared to Alienators one season. Fans fondly remember Godzilla for being intelligently written and for making the Godzilla from the ill-received movie cool again by having him fight monsters. Conversely Alienators is mostly forgotten.
MTV's Downtown (1999) Mission Hill (1999) Late 90's Adult Animated series about the bizarre city life. Both shows were released in 1999, they were well animated following artistic styles of Alternative comics. They were so unique and strange, too strange for their own good. They both had strange characters and stranger settings. They had many sexual jokes and nerdy pop culture jokes. Both shows lasted only one season with 13 episodes. Mission Hill wins only because it was rerun on [adult swim] after the show was cancelled, along with a proper DVD release (even though the licensed music has been replaced). Downtown's DVD release is only available online directly from the creators.
Family Guy (1999) American Dad! (2005) Dysfunctional Family animated shows created by Seth MacFarlane. American Dad was created a scant few years after FOX canceled Family Guy (Seth still had a contract with FOX, and they needed a new show since a lot of their live-action stuff was getting canceled — both justly and unjustly). Then, Family Guy came back, thanks to high DVD revenue and big ratings from being rerun on [adult swim]. In terms of quality, American Dad wins because it has better writing and feels more like that animated All in the Family series that Seth MacFarlane has always wanted to do (at least in the early episodes. When Family Guy got more preachy and political, American Dad! became sillier and more cartoonish, only without the cutaway jokes). In terms of numbers, ratings, and cultural impact, Family Guy wins.
Courage the Cowardly Dog (1999) Poochini (2000) Animated series about timed dog who discovers weird stuff in his surroundings. Both Courage and Poochini live with an abusive male owner. Courage has the upper-hand. Mainly because it had more seasons and merchandise, which Poochini lacks.
Batman Beyond (1999, Kids' WB!) Spider-Man Unlimited (1999, FOX Kids) Merchandise-Driven spinoffs of Batman: The Animated Series and Spider-Man: The Animated Series respectively, released in 1999. Both shows centered on familiar heroes with new Powered Armor costumes with Invisibility Cloak powers, in a dystopia. Batman Beyond was set in a Bad Future dystopia, centered upon a teenager trained by Bruce Wayne in the Batman role and somehow developed into a Darker and Edgier show than its predecessor, particularly in The Movie that was based on it. Spider-Man Unlimited - which was originally planned to be a Animated Adaptation of Spider-Man 2099 - eventually came to be about Peter Parker in an Alternate Timeline dystopia, where Beast Men ruled the Earth. Batman Beyond, which lasted for three seasons and inspired a full-length animated film. Spider-Man Unlimited was canceled after one season.
SpongeBob SquarePants (1999) Coconut Fred's Fruit Salad Island (2005) An eternally cheerful super-optimist in a nautical-themed world of anthropomorphic sea creatures/fruit annoys his fussbudget neighbor while having wacky adventures with his dim-witted best friend. Fred premiered on Kids' WB! at the height of SpongeBob's popularity, and the main characters of both shows act and sound extremly similar. The main difference was that Fred was a talking coconut who lived on an island with other talking fruit. SpongeBob by a light year — it is one of the most successful cartoons of all time, the cornerstone of Nickelodeon's empire and has lasted for more than ten years. Coconut Fred was hated by critics, canceled after half a season, and considered an Old Shame for voice actor Rob Paulsen.
SpongeBob SquarePants (1999) Fish Hooks (2010) Cartoon about underwater creatures living human lives. SpongeBob is set in an ocean and stars a sponge working in a fast-food restaurant, while Fish Hooks is set in a pet store/TV repair shop and stars a group of fish going to high school. Fish Hooks is also much more realistic in plot, fish locomotion, food, and scale, while SpongeBob is more cartoony. SpongeBob, no contest. It is one of the most successful, well-known, and well-received cartoons of all time, and pretty much is to Nickelodeon as Mickey Mouse is to Disney and Bugs Bunny is to Warner Bros. Fish Hooks, on the other hand, is relatively obscure, widely hated, and doesn't have the success or fans that SpongeBob has.
The New Woody Woodpecker Show (1999) Baby Looney Tunes (2002) Modern take on classic cartoon series. Baby Looney Tunes is the first Looney Tunes series with Canadian voice actors. Woody manages to last for 3 season, has fast food chains promote the show with toys and was Adored by the Network durning it's run on Fox Kids. Baby Looney Tunes on the other hand was Screwed by the Network and lasted for 2 seasons. CN never aired any commercials for new episodes.
Jackie Chan Adventures (2000) The Mummy (2001) Two 2D animated shows on the early 2000's Kids WB block, both of which have inspirations from the Indiana Jones series, both of which concern some ancient culture, both of which have globe-bouncing MacGuffin story arcs, and both have allusions to cinema. The Mummy is a bit Lighter and Softer than the two films before it (as well as the original 1932 Mummy, which was a horror film classic). Sony/Columbia/Tristar distributed JCA while Universal, who is the copyright holders of The Mummy, are behind the animated version. JCA wins; it managed to get to 5 seasons and a whopping 95 episodes, as well as have a small franchise that included a Game Boy Advance video game for the early 2000's. The Mummy lasted two seasons second season, but after it concluded The Mummy franchise was sent to the Netherworld for 5 years until the third Mummy reboot movie, Tomb of the Dragon Emperor in 2008; the only person from the other parts of the franchise to return for that film was star Brendan Fraser, and it's weak critical reception sent The Mummy series back to the Underworld. Universal eventually began plans to reboot the franchise again altogether.
House of Mouse (2001) Harvey Birdman, Attorney at Law (2001) Massive cross-over series that parodies the characters in them. While House of Mouse uses different voice actors to voice various Disney characters, Harvey Birdman has Maurice LaMarche voice half of the entire guest cast. The comparisons here are as different as day and night. For one, the 2 have totally different audiences in mind. House of Mouse is more a nostalgia trip for a more general audience, while Harvey is an adult swim classic. Also, the winner is harder to figure out for a number of factors. Not the least of which was Harvey's far less consistent schedule. While technically Birdman ran longer, House of Mouse got more episodes. Really the decision is a toss up that might also depend on your feel for the different intentions of the 2 shows.
Totally Spies! (2001) Kim Possible (2002) High school girls(s) must save the world from evil. While Totally Spies did have a recurring villian here and there Kim Possible had a much stronger Rogues Gallery in that they would appear more frequently. Said rouges gallery also got much more screen time than any of the villians in Totally Spies! Hard to say. Totally Spies! lasted on the air longer but after Kim Possible was cancelled following its third season, fan outcry was so extreme Disney put out a Post-Script Season four. Totally Spies, in its French dub, is more popular in Europe, however.
ChalkZone (2002) Foster's Home for Imaginary Friends (2004) A shy little brunette boy and his outgoing, scrappy blue imaginary friend have adventures with other made-up beings. The titular ChalkZone took place in Another Dimension and was more adventure / fantasy based, while Foster's Home was in the real world, was more focused around comedy, and didn't have ChalkZone's adventure elements. Foster's is the clear winner, with high ratings and critical support and having lasted six seasons and seventy-seven episodes, three TV movies, had plenty of merchandise, and is still reran to this day. ChalkZone only got high ratings during its' first season (before being Screwed by the Network in its' second), barely any merchandise, ran quietly for four seasons of forty episodes, and despite having a small cult following, remains one of the more obscure Nicktoons.
Xiaolin Showdown (2003) Avatar: The Last Airbender (2005) Plot-driven animated series inspired by Asian culture, about a group of pre-teens and teenagers who fight evil by using elemental powers. Xiaolin is a kid-centric series about the heroes collecting powerful artifacts and trying to keep them out of the villains' grasp. Avatar is a more mature series about a child who has the power of all four elements, which he must use to defeat an evil army. Xiaolin's four protagonists have power over one of the four elements. Xiaolin is set in modern times, while Avatars setting is a fantasy world with heavy inspiration from eastern cultures. Xiaolin is more action focused, while Avatar is more plot and character driven. But while Xiaolin aired first, Avatar had been conceived in 2001. While Xiaolin was popular and well received, and even gained a reboot, Avatar had the better plot, the better writing, the better characters, and more popularity, leading to a sequel series and a (badly received) live-action film adaptation (which was disowned by series creators Michael DiMartino and Bryan Konieztko, and was the last film to convince Hollywood that M. Night Shyamalan had overstayed his welcome).
W.I.T.C.H. (2004) Winx Club (2004) Animesque sentai show with Magical Girls. Somewhat similar shows that both originated in Italy, except W.I.T.C.H. has a bigger budget and scripts with less filler. Many of the similarities were introduced through the adaptations. In America, the Winx had broadcast TV coverage from day one while the Guardians started on cable, so the Winx ended up clobbering them ratings-wise and have now outlasted their dueling counterparts. However, WITCH wins out in terms of quality due to WINX being initially dubbed by 4Kids (Seen in anime circles as one of the worst dubbing companies in the world after a terrible dub of One Piece and an average Yu-Gi-Oh! dub, while WITCH has a longer comic series (Lasting from 2001 to 2012), and WITCH was seen as a better show overall.
Danny Phantom (2004) Ben 10 (2005) Animated Science Fantasy action comedies about a White Male Lead schoolyard reject/Hollywood Nerd who gains the ability to transform into a super powered form from a Freak Lab Accident / Imported Alien Phlebotinum that was connected to one of their family members, decides to fight crime and creatures like what he can become in secret, is the main combatant in a Power Trio (two guys and one girl), have a know-it all red-headed relative, and used a catchphrase that was "Going [Blank]", and is from families that hunted the creature he can become. Danny Phantom premiered over a year before Ben 10, and can be said to have started the craze of secret teen/child heroes that would come the following year. While there are a number of differences, Ben 10 gave Danny Phantom its greatest competition of all of the shows. The rivalry between the show's parent channels only upped the competition Though both shows were well received and are well remembered, Ben 10 is the clear winner here. Not Only did it have four seasons to Danny Phantom's three, but also three spinoff shows, two live-action movies, two animated movies, a reboot, and much more merchandising than Danny Phantom ever had. Ben 10 also became Cartoon Network's flagship franchise until 2010, where as Danny Phantom never exceeded shows like SpongeBob SquarePants, Avatar: The Last Airbender, or even its sister show The Fairly OddParents for that role, though for what it's worth it did seemed to be loved by its network for the time it was on.
Kaput & Zösky (2004) Hi Hi Puffy AmiYumi (2004) Comedy series about duo of friends travel the world. Both shows' leads are in Distaff Counterpart territory. TBA at this time.
American Dragon: Jake Long (2005) The Life and Times of Juniper Lee (2005) Animated Supernatural Soap Opera in which a young American kid of Chinese decent inherits the mystical mantle of a wise Old Master grandparent and gains supernatural powers, and along with an Annoying Younger Sibling and a magical talking pug dog, is tasked with protecting and mediating the Masquerade between the human and magic worlds. Apart from all of the main characters (except for the talking dog) being Gender Flipped, there are moderate differences in how the supernatural elements function. Though both shows ran for about the same number of months, American Dragon has twelve episodes over Juniper Lee (although this was a standard Disney practice of stretching out seasons). Juniper Lee however has the advantage of getting three seasons whereas American Dragon only got two and even a DVD release of the first season (albeit only in Australia). Of the two series though, American Dragon is more well-remembered, while Juniper Lee is one of the least-remembered Cartoon Network shows.
Avatar: The Last Airbender (2005) Skyland (2006) Animated series about a Kid Hero who must restore balance to a Crapsack World with the help of their energetic team. In both, the worlds are either torn apart by war or broken and the hero deals with the gravity of it. Skyland is a Canadian/French/Luxembourgish co-production known for its gorgeous scenery while Avatar: The Last Airbender is an American ''anime'' from Nickelodeon which became known for challenging what it meant to be an anime and a cartoon. Are you kidding? Avatar by several hundred miles! Not only does it have 61 episodes to Skyland's 26, but it also has universal acclaim from all levels of society, a just-as-well received sequel, several tons of merchandise, a fandom that completely transcends any other western cartoon's (though the Brony phenomenon might offer some competition), three video games, a well-known comic series, a live-action adaptation (though a horrid one), a number of awards, and its characters are widely cosplayed. Skyland, while meaning well, just didn't have enough fans, budget, or audience to become an even moderate hit.
Robot Chicken (2005) MAD (2010) Mashup of sketches and parodies of games, films, animations and everything else in media. Robot Chicken is fully in stop motion while MAD, based on the cult magazine of the same name combines traditional animation, stop motion and CG. Both air on the same channel. Robot Chicken wins. It's more well-known and it's still on (despite claims that it's gone downhill). MAD lasted four seasons and was canceled in 2013.
Johnny Test (2005) The Mighty B! (2008) & Steven Universe (2013) An unlikely kid protagonist has the power to change the world. Johnny Test deals with a young boy and his super genius sisters; Steven Universe is about a boy who lives with sapient alien space rocks and fight to protect the Earth; The Mighty B! is about a member of a Girl Scouts like group who seeks to collect all the "HoneyBee Badges" in order to become a superhero. Steven Universe totally destroyed the other 2. The show has a massive fanbase, merchandise and was Adored by the Network at some point. Johnny Test and The Mighty B were both Screwed by the Network, barley had any merchandise & ended up airing the remainder of their episodes on a dead-slot.
El Chavo Animado (2006) The Mighty B! (2008) Shows that center around a kid protagonist in world where adults act like children. Portia's mom is an expy to Quico's mom. El Chavo had higher popularity, merchandising and has a seventh season planned. The Mighty B on the other hand ran for 2 season and has no merchandise at all.
Squirrel Boy (2006) Will And Dewitt (2007) & The Nutshack (2007) Gross Out Sadistic comedy shows about 2 friends' misadventures in a Crapsack World. Nobody really talks about these 3 (Squirrel Boy was talked about when someone on tv.com compares it to Sanjay and Craig in 2013. While The Nutshack was talked about when Rebel Taxi and Mr. Enter mentions it in their videos). Neither. They failed to gain audience causing them to get cancelled.
Batman: The Brave and the Bold (2008) The Super Hero Squad Show (2009) Silver Age esque kiddy-shows with a focus on lighthearted fun. Brave and the Bold is still quite close to the comics in characterization, except much more far-out in its storylines, whereas Super Hero Squad Show is extremely OTT and wacky in everything that happens. Also, BTBATB focuses almost exclusively on A Day in the Limelight, prioritizing characters like Clock King and Green Arrow over The Joker and Robin. Both shows are quite popular, but so far Brave and the Bold is slightly more popular. Super Hero Squad Show will likely make more money thanks to being Merchandise-Driven, however.
Tak and the Power of Juju (2007) The Garfield Show (2009) CGI animated comedy series that centers around an Unsympathetic Comedy Protagonist. The relationship that Tak had with Chief is very similar to the rivaly to Garfield and Nermal. Garfield had 3 season and still running on Bommerang while Tak had 20 something episode but got cancelled before it could finish a season. However, the fan base on TV.Com had some way to bring it back.
The Goode Family (2009) Kung Fu Dino Posse (2009) & ''The Problem Solverz" (2011) A group of misfits solve problems around the town they live in.. Mr. Enter had already reviewed "The Problem Solverz" and "Kung Fu Dino Posse". Someone had requested him to review "The Goode Family" later on. Out of the 3, The Problem Solverz had 2 seasons while Kung Fu Dino Posse has mostly positive reviews.
Bolts And Blip (2010) Pac-Man and the Ghostly Adventures (2013) Shows about unlikely heroes in a futuristic setting. Both shows uses different Canadian voice-acting groups in their shows. Pac-Man has a slight advantage mainly due to tie-in merchandising and is already confirmed for a second season. Bolts & Blip lasted for one 26 episode season.
Monster High (2010) Wild Grinders (2012) Animated series about a group of six friends with an unique theme (monsters and skateboarding). Obviously, Monster High is a girl-targeted monster show designed to be somewhat educational while Wild Grinders is a boy-targeted skateboard show designed to be silly and somewhat stupid. Monster High by a country mile-It has more than 200 webisodes, 6 hour-long specials, 4 feature length movies, an ocean of merchandise, lots of partnerships, and more fans (male or female) than Wild Grinders could ever wish for. Wild Grinders on the the other hand, is vehemently despised, cancelled after 2 seasons, had barely any merchandise, and is blamed for being a complete rip-off of Rocket Power.
Adventure Time (2010) My Little Pony: Friendship Is Magic (2010) Insanely popular shows that focus largely on humor and (mostly) episodic character building. Both have a large Periphery Demographic despite a cutesy, lighthearted exterior, and both take place in a Fantasy setting that is still filled with modern elements. Friendship is Magic mostly consists of Slice of Life episodes (which later episodes dumped to focus on more adventure type episodes) while Adventure Time is known for being a little on the weird side. Another tough call. Both shows are critically acclaimed and are largely considered the best original shows on their respective networks. Despite getting their start at around the same time, MLP is in its fifth season while Adventure Time is in its seventh. Though it's generally thought that Adventure Time is the easier to get into and the more well-known show to casual audiences, MLP has a larger and more infamous fanbase.
My Little Pony: Friendship Is Magic (2010) Littlest Pet Shop (2012) Musical cartoons about talking animals on The Hub based on a 80s/90s toy line by Hasbro. Both shows have a main character interested in fashion design, a leadership specialist, and a pink Cloud Cuckoolander. They also share a voice cast, animation studio, music team, and some writers. MLP is a show that combines slice of life elements with aesops mostly about friendship and perseverance and typically has only one plotline per episode, while LPS focuses more on the slice of life aspect and either has single plots or divides into two separate plots, focusing on the escapades of the Token Human and the titular pets. LPS does have its fans and is still going strong, but MLP sparked a more famous Periphery Demographic (bronies) and is more well-known online.
My Little Pony: Friendship Is Magic (2010) Filly Funtasia (2014) Merchandise-Driven shows about colorful talking ponies. Both shows have villains, however the Fillies look more like traditional horses compared to FIM ponies. Friendship is Magic is an insanely popular show, so Filly Funtasia is facing tough competition. However, there is still a possibility of the show attracting a small fandom of which are those put off by the direction Hasbro took with the MLP pony designs in G3.5 and FiM.
Sidekick (2010) Teen Titans Go! (2013) Super Hero themed comedy shows where kid protagonist act like toddlers. Sidekick was green lighted to be Cartoon Network's third break though acquisition after Johnny Test and Total Drama. However there's rarley any commercials for the show As it currenly unknown if Cartoon Nwtwork would air season 3 of Sidekick, Teen Titans Go won because it was Adored by the Network more then the formal and has lots of merchandise (which Sidekick doesn't seem to have}.
Sidekick (2010) Brickleberry (2012) Vulgar animated comedies about four friends who work for a Pointy-Haired Boss type. Sensei Jimmy is an Expy to Bobby Possumcods. All the seasons of Brickleberry had already aired in the US on Comedy Central. Cartoon Network has yet to air the third and final season of Sidekick.
Hero 108 (2010) Scaredy Squirrel (2011) Cartoon Network animated series about animals going on war. Scaredey Squirrel green lighted to be Cartoon Network's 4th break out Canadian import after Johnny Test, Total Drama and Sidekick. 108 won because CN completed airing all the episodes, aired on Boomerang and has merchandise in the states (which Scaredy Squirrel lacks).
The Avengers: Earth's Mightiest Heroes! (2010) Young Justice (2011) Action cartoons about superhero teams from the Marvel Universe and DC Universe respectively, fighting against various villains of their respective universes and dealing with team-base drama. The Avengers: Earth's Mightiest Heroes focuses more on the primary hero team of it's universe, where as Young Justice focused on a younger team operating under and with their universes premiere team. Both also underwent a storytelling change in their second seasons, which Earth's Mightiest Heroes focusing on standalone episodes halfway through its second season due to interference on the production end while Young Justice had a darker focus in its second season. Both series ended by being Screwed by the Network, with Earth's Mightiest Heroes being cancelled to create a series that more closely reflected the Marvel Cinematic Universe, while Young Justice was cancelled due to its funding being pulled because of low toy sales. However, both shows are still regarded as shining adaptations of their respective universes by their fanbases. While Young Justice may have a slight critical edge, especially due to the decline in storytelling in the latter half of Earth's Mightiest Heroes second season, due to their similar fates, and Young Justice's multiple hiatuses, it's hard to give a definitive victory to either side.
Kung Fu Panda: Legends of Awesomeness (2011) Dragons: Riders of Berk (2012) Animated CGI tv-series based off hit Dreamworks Animation films. Despite both series being owned by Dreamworks, Panda is being aired on Nickelodeon while Dragons airs on Cartoon Network. Jury's still out on this one.
Scaredy Squirrel (2011) Danger Mouse (2015) The protagonist must outwit his foes in a World of Funny Animals settings. Danger Mouse had been requested to air on Cartoon Network by someone on Idea Wiki. Danger Mouse wins because it was a reboot of a popular british cartoon, already confirmed to have a second season & has merchandise promoting the series. Scarey Squirrel on the other wasn't even popular, barely has any merchandise and Cartoon Network is yet to air the third and final season.
ThunderCats (2011) Legends of Chima (2013) High Science Fantasy in a World of Funny Animals with the most important kingdom being that of the lions. The adolescent prince of the lions, thought of as an immature fool, must rise to the occasion and prove himself then the world's animal tribes fall into disarray. Both shows were produced by Warner Bros. and distributed by Cartoon Network. The Thundercats show did very well in the ratings, but the toy-line proved unsuccessful, which is likely what led to the show getting uncerimoniously Screwed by the Network. Chima on the other hand did well with the toys (It was a LEGO Theme after all), but the show was never all that popular. As a result, viewer reception easily gives it to Thundercats, largely considering Chima an obvious ripoff of the former. Chima may at least still have a place among the LEGO fandom, however.
Young Justice (2011) Ultimate Spider-Man (2012) Action cartoons about teenage superheroes from the DC Universe and Marvel Universe respectively, training under the world's greatest superheroes while dealing with everyday teenage problems. Young Justice is the more serious and serialized of the two, especially in its second season. Ultimate Spider-Man is more jokey, frequently featuring cutaway gags and slapstick comedy. It is also known for working An Aesop into most episodes. Young Justice airs on Cartoon Network, while Ultimate Spider-Man airs on Disney XD. Young Justice has the critical edge and is well liked by comics fans, with Ultimate Spider-Man suffering by comparison to its predecessor, and is generally hated by Spider-Man fans. Young Justice ended its run with its second season (after a lot of scheduling changes and hiatuses) while Ultimate Spider-Man is on its third.
Ultimate Spider-Man (2012) Teen Titans Go! (2013) Cartoons about teenage superheroes from the DC Universe and Marvel Universe Both shows are Denser and Wackier animated adaptations of their comics of the same name. Titans met with mixed reviews due to the non-existent plot and new emphasis on humor but was renewed for a second season with "successful ratings" cited. Ultimate has acquired a mixed reputation among Spider-Man fans, as it's coming after Spectacular, one of, if not the most well-received Spider-Man series. They are both currently still going with Ultimate having a two season head-start.
Gravity Falls (2012) Camp Lakebottom (2013) A group of kids find that the place they're staying over the summer has strange, paranormal events happening near them. Both shows air on Disney networks in America, but Camp Lakebottom is not an official Disney production, and it's produced in Canada instead of America. Gravity Falls. It's been on the air longer and it has gained more recognition and praise than Camp Lakebottom, which is new and relatively obscure.
Wander over Yonder (2013) Uncle Grandpa (2013) Animated series about goofy characters with sidekicks seeking fun in their worlds. Uncle Grandpa is a spin-off of Secret Mountain Fort Awesome, and both UG and SMFA are based off of a pilot short called Uncle Grandpa. So far, Wander has been more well-received than Grandpa. It helps that Wander's creator, Craig McCracken, already has two successful shows under his belt, while Grandpa's creator, Pete Browngardt, only has one poorly-received one.
Ever After High (2013) Descendants: Wicked World (2015) Animated shorts about the children of famous fairy tale and fantasy characters going to High School. The protagonist of both is the daughter of an evil sorceress who decides to follow a different path than her mother. Ever After High is a spin-off of the Monster High franchise which follows a similar premise with famous movie monsters. Descendants: Wicked World is the continuation of the Descendants film, which follows a similar premise to Ever After High, but with the Disney versions of these fairy tale characters. It's hard to say for sure which will come out on top. On the one hand Ever After High has been around longer and is a spin-off of another successful doll line, but Descendants: Wicked World has the aid of using the more popular and well known Disney versions of the fairy tales both are based on. Both franchises are popular with their target demographics as well. In terms of animation, Ever After High likely eeks ahead, as that's more of it's focus, where as Descendants focuses more on it's live action films. Ever After High has many more episodes released as well due to this.
Miraculous Ladybug (2015) PJ Masks (2015) CGI animation about teen (or younger) superheroes who battle to protect their cities and secret identities Miraculous Ladybug (or Miraculous: Tales of Ladybug and Cat Noir) is a French-Japanese-Korean production dubbed and airing on Nickelodeon in the US; PJ Masks is entirely commissioned by Disney Junior as per all their shows. While both have superficial similarities (including both having male cat-themed superheroes - very early promotional work for the Miraculous Ladybug dub listed her partner in crime-fighting as CatBoy ala PJ Masks) PJ Masks is clearly aiming for a younger audience with Disney Junior, while Miraculous airs on Nickelodeon's main network and NickToon towards older tweens and young teens. Too early to tell, though the difference in age demographics likely will ensure not too much of an overlap.
Teen Titans Go!! (2013) Yo-Kai Watch (2015) Shows about kids/teens who have supernatural powers that have a huge emphasis on comedy, are adaptations of something else and are adored by the channels they air on.While Teen Titans Go! is based on the Teen Titans comics and the 2004 TV show, Yo-Kai Watch is based on a video game, and because of it originating in Japan, the show aired one year earlier in that country. As of November 2016, Teen Titans Go! is currently the #1 kids' show on TV these days, and its' success led to Cartoon Network beating Disney Channel and Nickelodeon in ratings, making it one of four factors that caused Disney to make budget cuts in May of 2016. Yo-Kai Watch, despite having lower ratings and low game sales, has more merchandise than Teen Titans Go!, and also had a Fathom Event in movie theaters that played to sold out theaters. Because of its' better success with the target audience, Teen Titans Go! wins this duel.
