madara with speed equal becomes the most dangerous I would say.
All he needs to do is remain intangiable, get behind someone, stick his hand through their brain, and become tangiable. Conversely, he can just teleport them into his weird dimension once he's got himself close and that's is that.
The rest is still kind of a speed debate in terms of whose attacks will hit who first. For instance, would WB flexing his arm come at the Earl faster than his Endou buster? Ah, actually, I guess durability would need to be debate in terms of who can survive whose stuff as well.
Don't know about Byakuran.
