.... who was the last person this guy beat.....
You know, Sasuke never 100% beat anyone by himself in part 2 for ages. He had Bunta against Deidara, Itachi was rigged, Bee got away, Obito & Karin saved him with the Kage & Danzo, Itachi helped him with Kabuto & Naruto (+others) with all of the other fights after that until he sapped the Bhiju against Naruto.
I mean, Naruto DOES use other people's help--I won't deny--but that's the whole point with him AND his lineage. The Uchihas are supposed to be solo kings but Sasuke blew that up for years.
Now don't get me wrong about the two. I see them both as equals and always have. When comparing them I don't see one VERSUS the other in power, I see a giant meat hammer that crushes anything OR finely honed scalpel that cuts through anything--it's preference & style that splits the two, not power.
