Vash the Stampede VS Bullseye
Bullseye gets 1 hour prep and buys all the guns, knives and grenades he thinks he's going to need. Vash shows up with the standard arms: six-shot revolver and his hidden automatic round (no angel arm).
Bullseye is going for the kill. Vash isn't (cuz otherwise he'd just angelarm the place to kingdom come). Fight takes place in NY.
Who wins?
