Sasuke is naturally more talented than Naruto so he will probably use the Rinnegan better. While Naruto has an insane amount of stamina. This battle can go either way.
Sasuke has just as much plot naruto arsenal is complete of techs that preta path makes useless however sasuke has to switch between eyes while naruto can have bm & rinnegan at same time so tough one
Naruto wins mid-difficulty because of his chakra reserves. Sasuke would be done after like a couple of ST's and maybe a Preta Path; Naruto could use multiple Chibaku Tensei's.
The Ocular techniques of the Rinnegan are far different than the Sharingan and involve large scale Ninjutsu techniques, which is Naruto's specialty.
Sasuke is better at the special techs like Sharingan Genjutsu, movement prediction and Amaterasu control. Plus, as I will reiterate, SASUKE DOES NOT HAVE THE CHAKRA RESERVES FOR THE RINNEGAN.
