i still fail to see the huge unbalance your referring to =/
so its 6 pro to naruto and 5 pros to sasuke,
-weapons don't count, as its only a special sword because he runs chidori through it.
-Also space time jutsu? when did sasuke get one of these?
-Considering how extremely uneffective EVERY fire jutsu has shown (even amaterasu), it doesn't really do anything in my eyes of "balance"
-Kirin needs massive preparation and time to set up, and can't be used just anywhere.
Yet every move naruto has is like pure destruction, and kage bunshin is just getting better and better in its usability. Also his summoning isn't gimped by having its largest summon killed. he's also going to be trained pretty soon. As well as recieve kyubbi's full chakra potential.
The big thing sasuke has over naruto, is his natural ability (sharingan, elemental affinities) and speed & taijutsu. (although MS is a ridulously effective technique against naruto since he's weak to genjutsu.)
Naruto only has basic techniques because he was never taught anything specilized until recently, Whereas sasuke was born into being a "genius"
Sasuke's style alone just makes it seem unbalanced though, he's graceful, avoids attacks and plans his assaults and tries to do things efficiently.
Compared to naruto who takes hits until he gets one big hit in, and usually gets messed up every big fight. He's not fast, or incredibly stong, and also doesn't use a special weapon so he seems just that much more inadequate when compared to sasuke.
