Naruto alone Mid Diffs him, while Sasuke can push him to High Diff
Depends on several factors, alive? Probably hard to say. Madara while blind already speed blitz'd Naruto and his susano is most likely stronger than sasuke's. Unless kuramasano fights then it could go either way.
Plus EMS Sasuke never has PS either.

You are one of the manga deniers huh...
The armor around the kyuubi is PS armor, already been stated. And susano is developmental depending on your chakra, hence why kakashi with only MS could use a PS. Sasuke after adapting further to the EMS made a PS armor and sword for the kyuubi. That's not final or complete susano armor.
It still isn't PS. Wasn't till he gained Rikudo Chakra that he was able to use PS.
