obviously we've to take into account the susano'o difference and the attack difference too
PS is much bigger/stronger than that one
and that was a fuuton attack boosted by Baku
but Nardo Lava Rasensuriken is far stronger than that one too, and it's not only fuuton, it's fuuton + lava (earth/fire) + sage chakra
all we can do is guess really...
but if we imagine Nardo throwing one of those at Sasky PS and sasky tries to block it, IMO it'll at least cut the susano'o arm off and probably still cause some extra damage
don't think it can fully cut the susano'o in half, just part of it
in my expert opinion, nothing should be able to tank lava rasenshuriken. It should be impossible--the cutting attribute of the attack itself coupled with the very nature of lava should mean anything in its radius gets sliced like hot butter. The thing that makes it so dangerous though is its horizontal radius and quickness of expansion.
Susanoo ain't surviving coming in contact with it (along with anything else), it should be impossible
remember, this isn't an explosive technique like tbbr--which i don't think susanoo can tank due to instant vaporization--it's a cutting tecnique that should be able to cut a vertical susanoo if it gets caught. And that's that. Sasuke should survive seeing how he resided in the gem on its face
I highly doubt naruto is capable of destroying sasuke's most powerful defense without using his most powerful attack (bijuudamarasenshuriken). Susanoo gets damaged, but it's nothing it can't heal from.
