People are getting confused IMO.
Hinata is the better Taijutsu user. Her abilities are more advanced and she has more skill in the art of hand to hand combat. Sakura isn't really a Taijutsu specialist, her power punches are an ability which is more like a side effect developed from her medical training.
A lot of people have mistaken this thread as a Verse's thread, which it isn't. If this was a verse thread i would say that Sakura would win. Hinata has confidence issues which would get in the way of her ability to fight. None of them have won a Major fight in the series single handed, but Sakura did actively participate in the battle against Sasori. People say that Sakura couldn't of won without Chiyo, which i totally agree with. But i also think that Chiyo couldn't of won without Sakura. Sakura has more battle experience and a wider range of abilities.
