Good points all.
Landing in water or a marsh with gear extended (or fixed) in a light plane is pretty much a guaranteed end-over-end flip to finish inverted with the gear pointing at the sky.
Lack of stall is over-hyped by the canard manufacturers. As you say, a high sink rate once you get slow and power required is much greater than power available is equally fatal and often less obvious. I’d be more interested in Vmca issues with a twin than whether it can or can’t stall. Hyping that “It can’t stall even engine out” is demonstrating aerodynamic illiteracy. Or at least letting aerodynamics take a back seat to marketing hype.
