Go first two years of AF/NROTC before you are committed/obligated to the service. If you don't get the pilot slot, bail out. Graduate and go to OTS/OCS of service that gives you a pilot slot. Also, Marines have a college program that can get you a cockpit.
Considerations:

USAF: go fixed wing, competitive to get rotary. UAV 'pilot' a possibilty in career.

Navy: Service needs, but could be Fixed or Rotary. Better you do ensures fixed. Tailhooker opportunity. Minimal exposure to being UAV 'pilot'.

Marines: Service needs, but lots of Rotary. Better you do ensures fixed. Tailhooker opportunity in F-18/Sea deck time as AV-8B pilot.

I recommend all 3 services since I have been in them. Great people, different stuff enroute, but reality most go where they can get a pilot slot with chance at type airframe/career opportunity that suits personal character.
Best of luck.
