Beside the possibilities of each a/c, the image is important to some owners. Some will want to fly in a jet, even if the capabilities are limited, and others will be afraid of the jet image. I flew a KA 300 for a guy who didn't want to be seen in a jet, fearful of the image (a turboprop can be seen as a workhorse, a jet as a toy...). Could sound silly but that the way it is.
P.S. : Toujours pas de boulot Porco?
