Even without edo kages, sasuke has no sealing jutsu, amaterasu honestly just isn't taking oro down with his body shedding and eight branches techniques. Only way sasuke wins is if as always oro is weakened or he uses genjutsu while oro tries to take his body; oro with killing intent wins imo.
He has equal if not greater chakra reserves and is intelligent enough to find a way to bypass susanoo
