With the Juubi, Obito is obviously almost unbeatable by anyone... you'd have to be a special shinobi to challenge him there. Itachi is an elite shinobi, but not enough to overcome this.

That said, if he still had the Rinnegan and the MS but did not have the Juubi, then I would give it to Itachi. Itachi has less chakra reserves, no Rinnegan, no teleportaton jutsu... and even still. I commonly find on these forums characters being awarded wins in hypothetical matchups simply because the other side has more power. If Hidan vs. Shikamaru had merely been hypothetical and never actual, I think 90% of people would give it to Hidan. Same with Naruto vs. Nagato... Naruto wasn't even a chunin yet and had no Rinnegan, of course he'd lose, right? But no... Naruto won that fight.

Obito himself conceded that had he not kept some secrets from Itachi then the latter shinobi would have seen him dead. I agree; I think Itachi is better.
