depends on your career goals, I wouldn't mind flying a PC-12 for the rest of my career. would prefer a king air, but either would be acceptablePeople have been known to get stuck with flying other single engines after the caravan. If you want to fly something more than a PC-12 or TBM you will want a lot of multi time under your belt before hopping into the Caravan.
Unfortunately insurance rules and jets that are nearly center line thrust somehow have a direct link to multi pistons.
