There are varying levels of ranking within classes. Orochimaru may have been a low S, and Itachi could have been a high S. Madara would likely be something higher, but the 5 Nations have never seen anyone so powerful, so a rank hasn't been made for his level yet. Like I said, I think you would see a somewhat even fight between Kages and S-Rank. Kakashi is strong enough to fight Obito, and we know Kakashi is more than qualified to become Hokage.
Good point. :0
The only thing I could say is, however, if Kakashi didn't have the same Sharingan as Obito, I feel he wouldn't be all that close to Obito in terms of strength. Like if all Kakashi had was that second delay between abilities, like when Naruto fought Obito, he'd probably have been smashed a lot easier. But, I can't really argue with what you've said. Varying levels of S-Rank is completely agreeable. I just look at all the canonical S-Rank, the Akatsuki, and see them as being fairly overpowered. One on One, I feel that most of the Kage with have terrible difficultly with half the Akatasuki.
But, yes, fair point.
And it looks like we have a bit of continued use of the site now. haha
