i would prefer to be a line pilot any day. i have a lot of days off this month and there is no way i could get them working in the sim or as a ground instructor. so if you like the mon-fri job then be a ground instructor. if you want to make pretty good money but work crazy hours be a sim instructor. if you want the most time off and build flight time be a line pilot.
