If you go active you must embrace the concept that at every turn ITS NOT ABOUT YOU. Every door that opens or closes is based on the needs of the service.

That being said - I don't know of anyone that hated their assigned platform. I have flown props, light jets, helos, tactical jets and heavy prop aircraft and I think flying helos was the most "fun" followed by day carrier landings. Fighter maneuvers was challenging but not the "fun" I thought it would be. (About as physically hard as boxing out of your weight class). Low level Ops was "Fun". Probably the most rewarding was teaching and leading large formations and tactical elements. But you might get assigned the C2 greyhound which is not sexy but gives your more port calls than you can count and no night traps.
