Unlimited stamina and health isn't strength at all. It only makes it impossible for the Edos to actually be killed. Edo Mu isn't considered stronger than EMS Madara despite the fact EMS Madara is alive while Mu is an Edo. Same principle.
I said that Gai beats them. Hashirama doesn't beat either. Not to mention Edo Madara isn't apart of Kabuto's arsenal.
Sasuke casually cuts Chibaku Tensei orbs the size of the Shinju's root. No Edo Kabuto has in his arsenal surpasses Sasuke when it comes to raw power, so he's far above. Distance isn't even a factor here. If he's far away, he enters Susanoo, closes the distance and one shots Kabuto along with all his Edos.
Hahsirama never really broke out of the jutsu, so he should still be considered as apart of Oro's arsenal. Edo Madara broke the actual contract, Hashirama simply can't be controlled. He's basically the same as a summon. So no, Edo Hokage>Kabuto's Edo Army. BM Minato can power everyone up with the cloaks, or at the very least some raw chakra, which a 3x boost at the minimum. Without Edo Madara, they stand no chance of winning.
Rinnegan Teleportation isn't the bulk of Sasuke's strength, judging him by it does't make sense to me. His Susanoo would tear Kakashi's apart, and from there, it just depends on whether he can hit Kakashi and kill him, or whether he outlasts Kakashi.
That's probably it.
