Mr. CL601 pilot has been much more cogent and thorough in his analysis of a wider range of variables than my intentionally more general approach.

If acquisition and operating cost isn't a major factor with this class of aircraft than sure, maybe a legitimate argument can be made for the B200's engine and systems redundancy. But I'm still intrigued or play a devils advocate when I think of the PC12 burning 25-30% less fuel (and other significant cost savings considerations) for essentially the same performance/mission capabilities because this provides a savings hedge against possible future cost increases. I mentioned something earlier about my making an analysis for a company I flew for that argued for a "less" of an aircraft. Ironically this was because the company couldn't afford the purchase price of a upgrade aircraft that the same analysis indicated would greatly benefit their productivity.
