This isn't a very well thought out thread IMO no offense. Maybe it's just me but I don't like vs. arguments that deal with one person who we know a whole hell of a lot more of and another we have only hype on. We've literally never seen Sakumo throw a punch, just that he was revered throughout Konoha until he failed that mission.
With threads like this it's only who appeals more to people, Sakumo or Kakashi. It's nothing more then that, there's no factual evidence of ability to compose a real argument. It's just going to be dozens of posts like "Sakumo" or "Kakashi" with the ocassional added statments that say that one is more awsome then the other.
