Tobirama Senju will win for sure imho. Amaterasu and Kagutsuchi requires a brief charging period, which is enough time for Tobirama to create Shadow Clones and use Water Release: Exploding Water Colliding Wave to block it as he can move his hands extremely fast. He was able to tag Juubito multiple times as he tore his body in half, and living Tobirama is even stronger. He can outlast Sasuke in a battle of stamina, is reflexive enough to notice Amaterasu and combat it. He even knew what Amaterasu was when he was reincarnated meaning he's dealt with it before. Since EMS Sasuke pretty much spams Amaterasu and Kagutsuchi, I have no problem believing that Tobirama can counter those two.

As for Susanoo, he doesn't actually beat it, he simply avoids it's attacks until Sasuke gets exhausted. Or he can always warp it and Sasuke away to get rid of him.
