He doesn't need speed he can use the Body Replacement Technique...so if hit with that he would simply shed his outter layer. On top of that Kabuto has done extensive research on the Uchiha clan were Sasuke has only the intel from the time they lived together with Oro.

I say he is one of the best because there is no war without Kabuto...at least not a good one. There is no Oro without Kabuto as he was his right hand man. Which many wanted to be but could not. All the spy work he did on all the nations made him one of the most useful. All the experiment that he performed made him one of the most deadly.
