Not sure what diff, because they’re VERY close in power, but I feel like Orochimaru would try and tank a Rasenshuriken like he did against the tailed beast bomb from 4 tails Naruto
I voted wrong; I always get confused on whether he absorbed Kabuto's Senjutsu or not but then I remember he didn't absorb it and only absorbed his chakra that Kabuto injected himself with. Anyway, I'm going with Naruto high diff.
