@Jbhdbc: You mean after Minato, Obito, and Naruto, A is the four fastest ninja in Naruto. Before you say anything, it was stated by zetsu that Obito is light speed when he use his kaumi jutsu.
A The Raikage wins this. But Guy will be troublesome.
@PrinceAragorn1: RM means Rikudou mode. No Base Guy did not demonstrated to be around Naruto Rikudou Mode. That was plot dives, because he had trouble with a clone that only had 30% chakra of Kisame... And the fact that he had to go to the Seven Gate just to beat Kisame. He had help from Killer Bee and a turtle he summon just to catch up to kisame.
