not sure really. I feel as though hiruzen without the age factor hindrance and poor stamina is still a force to be reckoned with.
Plus Hiruzen uses shadow clones, which will really help overwhelm sasuke. All those massive elemental jutsu combinations, sasuke can't really defend them. Enma deals with manda the same way he did with kurama,except manda is way less powerful.
Hiruzen has Wind counters for Sasukes lightning as well as Water counters for fire techniques. I'm sure hiruzen has no problems against snakes, since oro was his student.
Ever since I saw sasuke fight Bee and the kages, I just realized how different of a league the kages were. Almost crushed by Ay, almost melted by Mei, almost one shotted by Ohnoki, Danzo was koto restricted against sasuke too, and killed 3 times by Bee. And that was MS sasuke for all those situations, hebi is even weaker.
