Greed vs Senator Armstrong

They have nearly the exact same powers and reflexes, speed, and durability. What would be the deciding factor in a fight like this one, as crazy as it sounds.

Greed is the Brotherhood version, and Armstrong has all of his abilities from both the main fight and DLC fight.

Who wins?

According to Spacebattles http://forums.spacebattles.com/threads/senator-armstrong-mgr-vs-greed-fma.252376/ Armstrong not only wins but stomps.

Bumb

Its not like greed will damage Armstrong even by 0.001%. Armstrong can regenerate too you know.
