These single engine turboprops are really impressive aircraft, very comfortable with sophisticated avionics and impressive performance but no matter how good they are and some have good systems redundance they lack the most critical redundancy, an additional engine !
This can literally be a life or death situation, there are numerous occasions where losing your sole powerplant will result in catastrophe, all the statistics in the world won't help you then.
I'd still take a piston twin, or preferably a twin turboprop over a SET no matter how nice.
