Um the fourth was definitely the most talented he just didn't live very long I don't even think he was anywhere near his peak when he died. I don't know why you think he defeated Oro being that he died and Oro didn't but defeating the kage zombies doesn't really mean much to me since they really were just zombies after Oro put that thing in them.

They really didn't fight much and weren't very competent because they were zombies ofcourse. If it wasn't for the fourth's jutsu Sarutobi would have not only died but he wouldn't have even been able to stop Oro during that battle so I would definitely say that Minato was more talented.

I never heard of this god of ninja thing before. What bad attitude?
