I don't think he is the best, but i also don't think he is a ''fodder'' kage. I mean he was called the god of shinobi, maybe it was something else than pure strength that made people call him that, maybe he was just a master of shinobi combat, being able to use alot of diffrent jutsu? We still haven't seen alot of him, but from what we've seen, he is definatly a really strong character!
