It is literally stated in the web comic that Saitama has no limits. The idea is that everyone is born with a limiter to their strength for various reasons and there is no way past that without becoming a monster and/or dying. Saitama managed to somehow break his limiter without either happening and thus no longer has a limit. While that is, admittedly, an explanation coming from another character, it's the only explanation that, to my knowledge, hasn't been shot down.
Let the joy of love give you an answer! Check out my book!Calling Saitama's power "just a gag" is pointless. Yes, it is a gag. But said gag is literally his concept. The whole reason he exists is to defeat things in One Punch. That is literally the whole point of the character. You could hypothetically speculate about his upper limits, but why? If you place a limit om him then there is no point for him to exist anymore.
If you make a crossover and include him, then he must defeat anything he fights with extreme ease because, otherwise, you might as well not have included him at all.
If you want a video speculating about Saitama's upper limits then here you go. It also talks about his entire point as a character, talks about the No Limit Fallacy that people love throwing around, and also compares Saitama to Popeye.
I would imagine those people who posed the argument by saying Cell would crush Saitama probably did. Then, when everyone was mostly done with the argument, people from both sides just sorta continued it. I'm not really one for vs arguments, but it is kinda amusing watching both sides talk around each other.

I love this one.
Then here's something else to talk about:
It's relevant because MasakoX talks as Goku in the beginning of it and there are clips from DBZA scattered throughout.
Let the joy of love give you an answer! Check out my book!I suggested this earlier but was apparently ignored.
He won the argument

We cool?

I'M MR. MEESEEKS, LOOK AT ME!Improving the story? The only instances I recall of them changing things from canon would be:
- Injecting mentions of things Toriyama added via Word of God.
- Tying the movies in as best they could. (Though they never did bring up the whole "Goku and Gohan aren't Super Saiyan for the whole of the Broly movie" thing.)
- Occasional small things like Wheelo living slightly longer, Dodoria being a woman, Nappa, etc.
Tailoring the story to their writing is more accurate anyway...
Improvement will be up to everyone else.
Rules of the Internet 45. Rule 45 is a lie. Check out my art if you notice.

Saitama is no limits fallacy embodied.
All anyone's doing is challenging the assertion that this should apply whenever Saitama is used in an online argument. I faintly understand why that's important but, it's annoying.
Should Saitama's gag apply outside of the series? Yes, I would say so, and because it's a gag, people shouldn't take it seriously. Because to say his shouldn't means that Bobobo's, Arale's, Bugs Bunny's, and Squirrel Girl's shouldn't either. People also shouldn't be saying "Saitama can beat Superman" as a counter to Superman defeating Goku in Death Battle, but they're going to anyway because this is the internet.
Can we move on?
