Familiarity: I've put it through the wringer
I've had a difficult time fitting snow/ski helmets and have tried on many different brands. I have a round profile head (if that helps) and the other brands I tried on were either too large fore/aft while being too tight side/side or they were too short fore/aft and too large side/side.
The Salomon Prophet Air fit nicely all around and has performed well in the park and out of bounds. I paired them with an Oakley Airbrake goggle and have no issues. The padding is soft and comfortable and the air pump system is easy to use.
I purchased the white/grey color and the only issue I've seen is that the shell yellows in color a little bit over time.
