If I ever reach a level when I could afford any of these I would not think a minute more and go for a twin engine aircraft...
Regardles of what they'll say, put yourself always into an Ifr night situation over the alps, and a compresor stall or fuel supply failure. Read those avherald infos on engine self shutdowns in flight on big airliners and think about your wife, family, etc.
DOC of a twin turboprop is roughly a 30% more in total than a SET. Is a life of a person who earned for an airplane like that worth those 30% savings ?
Cheers
