Well, it *would* mean it's better than the Searey, a similar airplane.
I took a look at my database. In about 30% of Searey accidents from 1998 to 2011 (14 out of 44), the NTSB referenced either a stall or a lack of airspeed control. "Stall/Spin" was specifically stated in only two of the 14 cases, but most of the cases appeared to have occurred too low for rotation to start.
In my opinion, the claimed resistance to spinning itself will be of little consequence (few GA accidents occur high enough for a spin to establish itself), but IIRC the stall characteristics themselves are improved as well. If so, this will certainly help. The Searey has a relatively low rate of fatalities (lower than the Piper PA-28 series, in fact) and it will be interesting to compare to the Icon, with its claimed occupant-protection features.
