naruto is a better mental character then sasuke.
sasuke is a better "true ninja"
naruto is a better person (he is not selfish and is caring a sterotypical hero)
sasuke is a horrible but honest person (a true anti hero since he teams with naruto if the situation seemed bleak for him 2nd movie shippuden series)
naruto: is much more powerful currently (Bijuu mode and perfect synch with Kurama)
Sasuke is much more versitile (multiply elements. Fire, lightning, sharingan (EMS), blaze release/inferno)
naruto's beliefs is just (that the old system is not right and that hatred can quelled through love and friendship)
Sasuke's believes = power, power, and more power and also fear.
Naruto's friends constantly rely on him.
Sasuke's friends minus karin is able to hold their own.
Naruto has mastered several styles of fight, Frog, Bijuu, and fox (yeah that little thing where he becomes horribly violent and has claws, yes thats a fighting style)
Sasuke is a master swords men and a better ninja tool user.
Naruto has more chakra (god like compared to others in the show. only edo's come close do to them being unlimited)
Sasuke does not have much chakra compare to people on his level of strength and may and may always get close to passing out if he wins and thats a if that is gonna kill him one day if he does not train it up.
Naruto tatical side rivals sasuke (he tricked: Pain, Diedara, oro, kakashi, obito/tobi) all of whom mind you are sort of God like intelligent and even shikamaru may not even compare.
Sasuke is more book smart and in slightly more battle smart do to his versitility, but if did not have that him and naruto would be on par.
Naruto learns through his battle and injuries he receives and how he can latter rectify it. (rasenshuriken being a sample)
sasuke has limit use of Chidori
naruto use of rasangan is that versitile (thrown, tossed, minimized, grown, create whirlpools, and even create multiples through of shadow shuirken or shadow clone jutsu)
Sasuke's sasunoo is a almost absolute defence
naruto's Bijuu mode is a absolute monster offensivly. if he wanted the villages would bow to him if he was evil.
Sasuke's offensive abilites are kinda limited (he mainly uses fireball, and chidori senbon for ranged but he has lot more close range. but his most powerful techniques require range. Karin, Amatarasu, bow and arrow (sasuanoo) )
naruto is a mid range fighter and close range fighter (he uses more ranged attacks (shadow clones count as range it is not you fighting but it is as a clone) thus he can keep many opponents on their toes)
Naruto can beat anyone through sheer effort and training. (pain, and several Akasuki members as example)
Sasuke can beat anyone but it is sometimes do to plot which in my case is downing his true character and thats horrible to do to him. ergo (Plot no jutsu sucks)
naruto stamina is godly the only one in my mind that can truely match it is SO6P (naruto has maintined his Bijuu, and KM modes for two or three days now. he has battled on several fronts.)
Sasuke has anger issues
Naruto also had some anger issues
Sasuke... (damn im running out here) has been given many upgrades
naruto... has fought or achieved them legitamately
Sasuke has achieve several do too him succeeding in just staying purely alive (Saiyan power O-O)
naruto strength comes from his will and love
Sasuke's comes from hate and evil
Naruto powers may extend far from what we are seeing now
Sasuke's potential is almost reached
naruto is faster and i do mean much faster
Sasuke is more book smart
Naruto is prankster
sasuke: is a stern and shrewed man
Naruto is well hyper active
Sasuke is laid back
naruto can control Bijuu completely and not repress them
Sasuke can only repress Kurama
naruto is a hero
Sasuke is a anti hero (not a full villian he plays on the side that will basicaly only make his goals come faster)
Naruto has saved sasuke many times
Sasuke has only returned that favor a few times
