Sasuke couldn't use Susanoo because SPOILER: he is temporary unable to use his mangekyo powers because he traveled to Kaguya's dimensions too much.

As for Naruto, well, Orochimaru was not able to pierce a 4-tail version of Naruto with his snake sword, yet SPSM Naruto was stabbed by Sasuke's sword. In comparasion, the same Naruto couldn't be pierced and took a chidori unharmed by Sasuke in their final fight. And no, Naruto doesn't need to willingly harder the Kurama chakra in order to not get stabbed or anything like that, i mean i'm pretty sure this is done automatically, hence the name "chakra CLOAK".Considering Naruto's previous feats, i don't really know what they had in mind when they made him get stab, i doesn't really make sense. Whatever...
