MS Sasuke>SM Naruto.
The only attack that can even hope of damaging Sasuke's level 4 Susanoo is Naruto's FRS. Except, Naruto only has 3 FRS to fire and Enton easily counters FRS by consuming it and making a bigger flame

The FRS is completely gone so than is BS about it being made stronger by the Enton and being a danger to Sasuke is false. It'll get consumed by the flame and turned on Naruto instead, which can later be used to take care of any clones. (Via Kagutsuchi)
V2 Susanoo was able to block off the majority of Kirin's damage, Sasuke's level 4 Susanoo easily tanks that. Even if someone wants to come here saying that FRS cut the Juubi's tails (Which is false, besides, flesh is more prone to cutting and slicing than it is to explosive damage) Its not like FRS will ever hit Susanoo anyway.
No Rasengan of any kind is getting past a level 4 Susanoo or even damaging it, not in a million years so no one mention that either. Not when Kyuubi took more visible damage from FRS, not when FRS is his strongest jutsu.
Toad Summons are completely useless as they get casually one shotted by Enton projectiles. (Which Sasuke can shoot from his level 4 Susanoo due to the Amaterasu orb being present)
No one mention Ma and Pa cause even if Naruto can summon them, we've already seen that it took Jiraiya a whole chapter to call on them, and he had to have his hands clapped together. That leaves him vulnerable to Amaterasu as he would have zero defenses capable of making a difference.
Naruto either ends up getting hit by Amaterasu or he gets hit by an arrow after Sage Mode runs out either due to the 5 minute limit or his FRS limit
MS Sasuke wins this, especially with full intel, waiting for someone to explain how he wins cause with Enton easily countering his strongest move, there is no chance of his victory.
