I was told upon joining that as soon as you start your career you should start to plan for leaving. And on that advice I'd have to say that a AET will have a far easier time getting a better paid job over an AH. However when your young your not thinking 20 odd years down the road and to that end a job as a AH may appeal more. If you like the idea of driving fire trucks, rescuing pilots from crashed aircraft, belonging to a tight "band of brothers" type group, being generally fitter and getting the lions share of the women then AH is for you. If tinkering with nuts and bolts, washing helicopters and being stuck in the Hangar when all the other lads are bronzing on the flight deck then definitely AET.
