ummm oro would only win if kishi updated the 1st and 2nd's power levels and jutsu . the edo's we saw in part 1 are nothing compared to kabuto or his set of edo's
Kabuto could probably take control of the edos. If we're talking about Orochimaru, the way Hashimara is currently being spoken of, and the second Hokage Orochimaru purely due to OP Hashi.
kabuto since hes reanimation jutsu doesn't make them weaker and he has edo madara who is taking on the hokage easily and kabuto has all the other edos and he has sage mode with powers of those hree clans
