Well this may be true but keep in mind that Sasuke uses the rinnegan differently from what we've seen for all we know Sasuke can use Naraka path to take in a whole bunch of people into the "king of hell" and turn them into his personal slaves (not saying he can just an example). he could probably use Asura path as a catalyst to amp up his jutsu, idk the possibilities are endless, he could even have techs we haven't seen as the eye does come from the sage so that fact still exists. I'm just saying that people are continuously comparing Nagato's use to Sasuke's and using that as a basis against his fight with Naruto when everyone knows that Sasuke is 1)leagues above Nagato 2)Uses his Rinnegan ability differently than Nagato 3)In terms raw power and ability, sasuke's use, even with an unmastered Rinnegan was above Nagato's whom(not even at full power) took out KCM Naruto.
I don't see how Rinnegan techs doesn't help Sasuke much
Preta Path: Takes time to absorb large techniques. Sasuke doesn't have feats regarding dealing with raw natural energy.
Asura Path: Why even use it when Susanoo is a far better option
Human Path: We've seen that the user needs to make the target bound somehow. Won't happen with Naruto. Also Naruto can always play tug of war for his soul, which he'll win easily, given his far superior physical strength than Sasuke's.
Anima Path: As useless as it gets
Naraka Path: He's gonna bring himself back to life?
Deva path: Shinra Tensei won't even put a scratch on Naruto. And what will rocks even do to Naruto? :lol he'd destroy any rock attracted to him with chakra hands.
