Despite it getting a little wacky at the end, as per the norm of the show, no one can deny that Lee and Naruto's fight against Sasuke was a feast of these.
Chapter 35 of the manga: Tenten's in over her head as she tries to help Tsunade with her duties, but she manages to fight off Orochimaru and Kabuto at the end.
The manga's final chapter. After all these years of suffering The Worf Effect and jokes at how Lee never wins, Lee finally manages to defeat Gaara in a one-on-one fight. Even more importantly is that unlike the fight against Sasuke in the anime, Lee beats Gaara with zero gags whatsoever.
