Lol, waiting for someone to actually post an argument.
-BM Minato is fast enough to evade Kamui on foot let alone Hiraishin.
-BM Minato can spam clones, Kakashi can't snipe them all at once.
-BM Minato has the power to break open Susanoo, and he has the defensive capabilities to block its attacks.
I don't know why this wank is so strong, but Kakashi hasn't shown anything at the moment that would let anyone logically put his Susanoo on the level of Sasuke's. Why is everyone assuming its better than Madara's? Cause that's the only way he'll beat Minato here.
Until Kakashi's PS gets more feats, Minato still wins every scenario bar the first.
