As everyone has pretty much said here, no question, Kingair 200. The Kingair will fly on one engine, the PC-12 will ONLY fly if that one engine is running. Its all great in a PC-12 until that one engine quits and you go skidding through the Walmart parking lot. P&W PT6's are very dependable, but it is not unheard to lose one and have to shut it down, we did in the Kingair 350 we used to have. Imagine if you were in that PC-12 and had to do it!
