The Piper has a bulletproof Pratt & Whitney engine, The Mustang has two engines, so both should be good. The Piper has some issues with pilot error, too much power for some amateur pilots. The Cirrus has a parachute system, but I guess you need to get up in the air to use that. I see a lot of crashes are at take off. Also, you need to pull the lever. They do seem to have a problem with pilots waiting too long to deploy the parachute, as it sort of wrecks the plane.
