Familiarity: I've put it through the wringer
Crowbars have a nice consistent feel on the face. Fits in helmets, good breathability, but mind you common sense must be used, such as you can't really hike in goggles unless the temperature allows. Or placing them on forehead for any extended period of time. G30 is my favorite, the Rose is the newer G30.
