dont worry once you see the full potential of both characters, you'd be really leaning towards naruto...
NARUTO'S ASSETS TO DEFEAT SASUKE:
1. naruto sage mode (even its limited...he can still kick sasuke's ass and rip him in time; just imagine he took out 4 pains with a sage mode, unscath; meaning its like defeating one team of jounins...)
2. naruto sage making kagebunshin = shadowclone unaffected by sharingan
(ex. kakashi vs itachi: kakashi hid himself underground while in the hidden mist technique while his clone attacked itachi, when itachi tried to put the clone in genjutsu nothing happened...) with naruto's present skills he will definitely be efficient in shadowcloning thus making him unaffected by genjutsu...
partners to disable genjutsu: sage clones, kyuubi
3. sasuke's attack chidori can be disabled by wind...hopefully we'll see naruto having wind shield as well; like when sasuke protected his body by chidori...so lightning element would rendered useless...nwei it would really be rendered useless with his rasen shuriken...hehehe
4. naruto has immense reserved chakra; sasuke doesn't have that much especially when his cursed seal + oro inside him was destroyed...
5. kyuubi will not be controllable now that it has a host / partner...madara controlled it several years ago only because the kyuubi was all alone, making it susceptible to genjutsu / hypnotism...but now with a strong partner / host, i doubt it would ever happen again...
(ex. the eight-tail jinchuruuki)
SASUKE'S ASSETS TO DEFEAT NARUTO:
1. Fire element; he can use chidori to lure naruto in using his fuuton rasen shuriken then quickly stop and throw the grand fireball to him...making the grand fireball stronger because of the fuuton / wind element...
2. Sasuke's speed + sword skills...he can rely on this without using much ninjutsu...while naruto doesn't have anything in his arsenal except his fist, hmmm i really doubt that this sword will pierce thru naruto - remember the pointed rocks in frog mountains? once in sage mode his body became very stiff = this im really not sure of...hehehe
3. last but not the least; sasuke is more smarter than naruto...
well hopefully this hardworking guy kicks ******'s ass soon, im sick and tired watching him unscratched when he battles naruto...its payback time
