Thoughts:
-Vamp has the reflex advantage, having dodged bullets from the last SEAL's gun.
-in actual movement speed, he is probably equal-to-slightly-above Krauser. They both make large leaps and Krauser was flipping around gunfire and stuff when Leon fought him in the ruins. He also covered a large amount of ground in no time after setting off a flash grenade.
-Krauser is far above Vamp in terms of actual shown durability and knife-to-knife combat. Vamp seemed to prefer stealth and throwing his knife to actually getting up close to his opponent.
