As GreatestSin said, Sasuke's rinnegan seems "stronger" because he has extra abilities, like teleporting through Kaguya's dimensions. It doesn't necessarily mean Sasuke would beat Hagoromo. However, it seems Sasuke's rinnegan is superior as of now, due to the fact that had Hagoromo's rinnegan possessed the ability to travel to Kaguya's dimensions, he would have sooner or later found out about those so-called guys who are supposed to be "worse than Kaguya" (the villains of Boruto: Naruto the Movie). He also would probably have found out about Black Zetsu's schemes after gathering info on those dimensions. But he couldn't. So I'd say that Sasuke's rinnegan has the potential of having far more significant implications for the shinobi world when compared to Hagoromo's rinnegan.
