Kakashi can spam Kamui and has better Stamina/Chakra reserves now.
Kamui to the head of Sasuke and its all over.
Sasuke does have Susanoo but that can be taken care of plus the arrows....and Kakashi is more efficient with Chidori/Raikiri
Imo Kakashi>Sasuke still.
Anything Sasuke throws at Kakashi gets warped.
If you think otherwise please post a reason why and genjutsu doesnt apply as Sasuke's genjutsu doesnt compare to Itachi's
