If everything else were equal (pay, schedule, bennies), I'd choose a Pilatus PC-12.
It may sound funny, but the 18 months I spent flying one was some of the most fun I've had in aviation in many, many years.
Otherwise, like the others have said - I'd only care about which was the better JOB, rather than which was the better plane (although I think the 7X is kind of a homely looking airplane compared to the other 2).
