I would have to say Sasuke, since Neji was defeated by NARUTO! If you get defeated by Naruto, you can't be a genious! And as for Sasuke, he survived being sealed by Orochimaru, nad has mastered Rock Lee's super taijutsu, Kakashis thousand birds-thingies.

BUT

Neji is cooler.
losing to naruto doesn't mean anything, he is the main character for god's sake. naruto can't lose. except against kimimaro, but that won't be a loss, more of a "damn, he escaped and i am preoccupied therefor, i cannot follow him so this will be a loss" sort of thing.

but as vagabond said, if it was about potential, then sasuke would crush neji. sasuke is a late bloomer!
