I'd go King Air. Wait! Wait! I know you're shocked! Oh, no, you aren't.
The King Air has the ubiquitous ramp presence that can't be beat, plus they're all over for a reason. They're workhorses that are comfortable and reliable, with a good useful load and features. Plus, you've got two engines for when one fails.
The biggest positive from the King Air in my mind is that you can buy older ones that really aren't much different from the newer ones. The PC-12 hasn't been around as long, and you ultimately get more for your money with a used King Air. Now that price differential can easily be made up, but you're looking at a similar footprint (and thus hangar bill), etc. There are also more King Air varieties to choose from. PC-12 is, well, PC-12. King Air you can get a 90 (and many different 90s), 100, 200, 350. So long as you stick with a 200 or smaller you don't need a type rating, just your insurance-required training.
