So it's a 3 vs 1 then? They're not naruto's kuchiyose no jutsu so they're external help. External help that can pull nin jutsu, gen jutsu and tai jutsu. Give Sasuke Itachi and Shusui then as external help, how does that turn out?
If Naruto fights alone, he has zero chance of escaping Amaterasu. Obito needed Izanami to counter it, 3rd Raikage lost an arm, 8 tails used 8 tails chakra and naruto used kyuubi chakra.
Is there anyone else who countered Sasuke's Amaterasu?
Naruto also loses to Sasuke's Genjutsu. He only had a counter because of the kyuubi.
MS Sasuke, perma or not, beats Naruto without moving a finger.
