Marine Corps all the way (okay, I might be slightly biased ). I was in a gun squadron that traveled a fair amount with our planes, so we got a chance to visit many bases from all branches and overseas allies. USAF had top notch facilities, best chow halls, treated the best, etc., from the bases I got to visit. Loved going to AFB deployments, but USMC is still way to go even if you don't get all the bennies that USAF or some of the other branches get.
