Okay but he had the fox's chakra to rely on, so that doesn't really mean anything. Without it he wouldn't be able to make that many clones nor could he sustain them for very long.
On another note, most of the people here are underestimating Sasuke in a big way. You shouldn't assume the sharingan is his only source of power, that's ridiculous. He still has the same physical skills and powers as he would without it, this isn't a "what if they never had their powers" its just a fight where they do not have access to them. He still has all his techs, sure using the chidori isn't a bright idea without the sharingan but it isn't impossible and would probably work on an opponent like Naruto.
Sasuke would still have his speed and raw ability, he just wouldn't be able to maximize his potential and would react slower than normal (not slow, just slow-ER). Take for example the Fourth Hokage, as far as we know he didn't have an KKG nor did he have some outside source of power. He had his genius and raw talent and still accomplished feats of strength that put him in the legendary status. It's just an example of how the sharingan isn't necessary to be a powerful fighter.
This is probably my last post in this thread so I'm going to conclude with the basic reasoning's I think Sasuke would win:
- Faster speed and reaction time.
- Much higher intelligence.
- His killer instincts means he doesn't hold back.
- He still has a powerful arsenal of techniques, with maybe the exception of his genjutsu.
- Lastly but probably the main reason: Naruto doesn't have his bijuu nor his sage mode to support him. This is huge because he cannot make sufficient clones to battle Sasuke in his normal style of fighting, nor can he tank hits like he normally can. He would be much more frail, his strategies would diminish and his overall ability to fight would be much more crippling than Sasuke's lack of sharingan.
And again, this is all according to the original thread post. My analysis would greatly differ if they had access to more of their abilities. The overall problem with this thread is nobody is actually reading other's posts and debating on what would and wouldn't be relevant. Instead you see everyone say "so and so would win" and maybe provide one example why, even if they were wrong and had their facts mixed up.
