If he was wiser, he could have sensed that obito was toying with him. he would have understood what his bro did and why.
In battle, he have a little more strategic sense than the MC, true, but it not enough to make him stronger to beat him.
Kishi never nerfed Sasuke ( nor naruto), he got him up through the whole series in a stupid way. ( the kid that beat by a hair a weakened Itachi, the kid that got nearly destroyed by the Kage, with just eyes changes and no training can fight on par with them, that's what I call Bulls**t.)
Naruto have more guts, more stamina, he is unpredictable, and he have a better insght when it concerns people.
Sasuke is like kakashi, if he doesn't shoot down the ennemy fast, he is done since he is not a powerhouse like itachi. that's why he had to put sasuke in battlefield at the end of the war in order to have them in a close state of chakra reserve, otherwise at the thrid part of the war, sasuke would be useless by exaustion.
( Don't forget that when sasuke and his group made a walk through Konoha and stuff easy peasy, naruto was fighting like a bull.)
If two of them in full condition are to fight, naruto wins by destructive power,speed, stamina and guts ( with a very close call I admit).
