Id like to say 1st that i dont **** with most of the people above me because known of you came up with a real reason for either of them to win. like 3 people said naruto by feats, his feats arent fighting the fight he is smfh.
Naruto wins because he has the upper hand in almost everything
Taijutsu sasuke would have the upper hand because of sharingan if naruto couldnt use the wind to attack like he did to preta path
Ninjutsu Sasuke has the advantage but since MS sasuke basic battle stategy is to hide in suasnoo and spam his jutsu(as seen in MS sasuke latest fight with danzo, which he had no real reason to fight like that since was obviously the better ninja and killed danzo 10 times in 1 fight). Naruto reasegan shuriken will not only perhaps smash suasnoo but it will damage it considerably and force sasuke to create another an weaken his chakra considerable since he's only EMS. But however like i said sasuke has the advantage as long as he fights and doesnt jutsu spam suasnoo. His lightning and fire style easily put him ahead of naruto in ninjutsu.
Summons sasuke only has the hawk, he doesnt have the snakes anymore and i doubt he'll be able to use sharingan and control the frog and fight naruto. Not to mention sasuke has not shown the skill to control anything with his sharingan so im not sure why people keep saying that. But something like the food chart jutsu or whatever its call will 1 surprise sasuke, 2 perhaps break his suasnoo, and 3 hold sasuke down. And with Ma and pa that only makes things worst.
In genjutsu sasuke would have it if naruto didnt have ma and pa 1 to wake him up from genjutsu and 2 to use the song genjutsu that sasuke has no ansewer for that we know of.(this genjutsu is said to be stronger than itachi's that sasuke supposingly broke in the fight with someone who wasnt trying to kill him at any point and was holding back the whole time)
And in intellegance they would be even but once again since naruto has Ma and Pa 3 heads think better than 1.
And sasuke down fall in this fight(only if he behaves like he normally does) is that he will use his sharingan to much and end up like he did against kakashi, and then its game over.
So naruto SM has the advantage in this fight and has a 75% chance of winning if he's set to kill and not set sasuke no i dont really wnna hurt you, why are you doin this...
