The biggest thing the SF50 has going for it is the parachute. To the non-pilot having a whole plane parachute is a significant comfort. I'll go on record saying that I'd love to have a whole plane parachute- it would be a nice to have safety item, but clearly I don't consider it a necessity .
Take the parachute out of the mix and I don't see the value of the SF50. I wouldn't say the M20TN as the competitor, but buy a Piper, TBM, Pilatus and you're probably better off. However, If the flight characteristics are similar to the SR22, a high time SR22 pilot could be safer near the edge of the envelope stepping up to an SF50 than other of the options. The SR22 is a great plane, but for the price I'd rather buy a G36. We'll eventually see how the SF50 compares to its competitors.
I do think that Cirrus is doing great work bringing innovation to GA though Garmin/avionics. The integration of the perspective system is impressive and the keyboard brings a usability that's a step above a standard G1000. I think the hypoxia functionality in the autopilot is a welcome addition to GA. However, not sure I'd get that excited about an integrated satellite phone.
