After having co-owned both, do you prefer the King Air or the Citation?
Citation by a lot. Quieter, smoother, faster, easier to fly. After owning both, and comparing prices of the King Air and Citation 510 and 525 series, it's hard to understand why anyone buys a King Air aside from short or unpaved runway situations.
The biggest advantage of the jet versus the King Air is the higher altitudes. Flying the King Air in the summer, I was always getting bounced around in the mid-20s. If there was a line of storms, I would wait for better weather. In the jet, I can pick my way around buildups of even the highest squall lines. There will be buildups into the 70s, but I've always been able to deviate a few miles and fly over tops in the 30s.
As far as safety, V1 cuts in the jet are a non-event compared to the King Air.
I think some pilots are scared of the type rating for jets and some owners perceive jet operating costs to be far higher compared to turbo props. With insurance training requirements, there's not much difference between jet and King Air training. Operating cost per hour is slightly higher on jets, but when you break it into cost per mile, they're similar due to faster speed.
I know several people who have gone from King Air to Citation. I don't know anyone who has gone from Citation (or other jet) to turbo prop.
