A random Namekian sees them fighting and ki blasts their asses into the oblivion. Jokes aside, Naruto wins by feats but in my opinion they are equal just like their counterparts with Rikudou Chakra.
Rinnegan Sasuke shouldn't be compared to Nagato's Rinnegan when he has a superior quality of Chakra and awakened his own Rinnegan, but the boost with having Full Kurama is too much here, so Sasuke would ultimately lose here.
You could say that before Naruto had Full Kurama. He'd easily stomp Sasuke at the point the OP is putting then against each other.
