Spider-man can dodge bullets, Venom is superior so he's faster, Carnage is superior to Venom. Carnage is insane and actually controls his symbiote while Eddie had to take some time to control his. I don't know much on Vash but if he shoots at Carnage will deflect, tank it, or dodge it. I like to think that Carnage is faster, just my opinion. I need more posts on Vash.
