Sasuke wins easily,
Ameno’s Naruto to him and snatches his soul out using the Human Path before Naruto can even acknowledge what happened.
But let’s say that the fight drags out, and Sasuke isn’t nerfed. Naruto’s bijuu Rasengan are deflected via shinra Tensei bursts OR absorbed by Preta OR teleported back at Naruto via Ameno OR are shot through via Asura Path’s blaster. Also, Sasuke should realistically be able to take Naruto’s chakra from a distance just as he did with the Bijuu that were trapped in the Chibaku Tensei. Sasuke could teleport Indra’s arrow right into Naruto, use genjutsu to tame Naruto, and a few other things. He could also cover his blade and Susano’o armor with Amaterasu and use enton to kill clones as they surround him. And it’s not like Sasuke can’t use Shadow clones too but whatever, that’s enough.
On the other hand, Naruto’s TSB are vulnerable to being Ameno’d away and Wood Release is useless against a Bijuu powered Perfect Susano’o. Shinra Tensei, Chibaku Tensei, Asura Path’s explosions, etc all get rid of the forests. Naruto has the upper hand if he’s able to use Wood Clones (cause let’s face it, he’s a one trick pony and he’s going to use Wood clones) because Sasuke hasn’t shown the ability to differentiate Wood clones from the real person. However Naruto could also boost all of his clones chakra to boiling point and hand Sasuke his ass if Sauce’s reaction time is lacking. Naruto can make limitless clones though and all of them will chakra at boiling point using frog kata COULD be trouble but Sasuke has a sharingan and can see chakra, so he should be alright.
Sasuke takes this.
