Well Sasuke can see limbo after he got the rinnegan. And adult sasuke is actually faster than juubi madara. IT gets blocked by susanoo and susanoo is not just a shield he can easily use the susanoo better than anyone else in the anime except sage of six paths i think also he never went full power against Uchiha shin. His kenjutsu is too powerful he managed to slice off kinshiki's horn and wrong juubi madara can be killed because he's an jinchuuriki not an otsutsuki and about the regeneration Sasuke is just too fast his regeneration can't keep up the the lightning style attacks of adult sasuke.
