Who would win Vash or E. Elric?

I have been bothered by this question for a while and do not know Ed with his alchemy and the ability to transmute without a transmutation circle or Vash the stampede with his superior aim and agility?
Please give a reason.

Personally i believe vash would win for his ability to dodge in a very animated way.

I voted for Ed, he would probably just transmute anything around Vash into metal and crush him to death.

Vash, because I just think he is more creative than elric even with just a gun.

Vash.

Just on the sole basis he can avoid your attacks running like a cockroach.

Even when Edward could summon 'The Gate.'
