Besides, I don't understand the whole idea of arguing over power levels in manga :S Especially on Naruto where the power levels are never kept constant and the writer fails to stay on his word. For example, you remember when Orochimaru summoned the 1st and 2nd to fight the 3rd? If it were the same 1st and 2nd from right now the third would have died almost instantly. Instead the fight lasted long. I think at that time Kishi didn't have the whole "Hashirama's OP and was the strongest ninja to ever be alive" at that time.
I don't know if it was pointed out in the manga or if it was in the anime instead, but Oro's Edo tensei at the time wasn't perfect and the first and second came back severely weakened compared to when they were alive.
