Ok, I've done some number crunching and come to the conclusion that the EU would win:
From here
US troops + reserves: 2280994
European troops + reserves: 5068910
From here
Eu population: 461,500,000
US population: 299,948,376
from here
GDPs about the same
Couldn't be bothered to assess comparative arms strength (planes tanks etc).
