Ninja Of War wrote: Not enough info or feats on Prime Hiruzen so can't say either way. True, but we do know he got the nickname The Professor because of his mastery or skill of every technique that exists within Konoha (that would also include Hiden techniques) and we do know that he was way more adept at using Shadow Clones in his prime. Hell, edo Hiruzen's clones could each use nature transformation during the 4th War. It would be hard to reach a final verdict, but I think that Prime Hiruzen could at least give Itachi a run for his money.

But yeah, other than that, I agree.
