Sasukes Rinnegan is not his own. It is Hagoromo's. He gave Sasuke that eye power. It's impossible to draw out the full power of the eye if it doesn't originally belong and was awakened by you. People keep saying:
"Why Sasuke ain't using his Rinnegan abilities?"
"Sasuke got nerfed, where the six paths abilities?"
"Sasuke got rusty like Naruto so he gotta practice his Rinnegan."
All of those are wrong. It's not that he isn't using them. He hasn't been nerfed. He's not rusty. The truth is he can't bring out the full power because the eye isn't his to begin with. He can't use it to its full extent. Ameno is a good technique and compliments his fighting style well he doesn't need the six paths techniques anyway. His eye is linked to Kaguyas dimension so that's a plus too.
Point is, it's Hagoromo's eye and Sasuke will probably never be able to bring out its full potential but even half of it is enough for him to be the second strongest shinobi in the world.
