A mask is good if:
- silicone skirt, not the cheap stuff
- the frame and skirt fit your face (should rest along the contour of your face when looking up at the sky and placing mask on face without inhaling)
- decent field of vision
- can reach the nose pocket, preferrably using only 1 hand
- secure strap connection to mask frame (ones that will rotate and disconnect, bad)
- avoid the honking high-volume masks if possible, easier to clear the old- fashion way if needed
I prefer to not use a purge, but it's not to say that you can't just make sure:
- keep your mask away from sand, it likes to get suck in the purge and make them leak
- make sure you are proficient in clearing the old-fashion way, and practice this from time to time
