Current Sasuke vs Current Kakashi
Alright, so we have this new chapter showcasing Kakashi's new powers. He apparently received a sizable portion of the Rikodou's chakra from Obito, and possesses both Mangekyou.
His Perfect Susano'o seems pretty equivalent to Sasuke, and his Kamui is honestly superior to Sasuke's STJ, considering how it allows him to slip through attacks as well as teleport.
Not only this, but Kakashi now has ST type attacks, which seem just as or more effective than Sasuke's Amaterasu type.
So who would actually win in a fight between these two? It seems stupid for Kakashi to be able to top Indra, but the entire last couple chapters have been pretty stupid.
