Army Infantry (Air ult) Vs. USAF Aerial Gunner? I can't decide which to enlist into. Any suggestions?

Need some help choosing. Any soldiers or Airmen who know a bit about these would be much appreciated. The Air Force enlistment will be 1 year longer than the Army enlistment but I just need opinions on which is a better, more exciting, and more enjoyable job. Pros and cons would be great too but i'm just looking for any advice to push me one way or the other. Thanks guys.
