I've got the matrix, alien and micromask as well as one of those 'beaver' masks (its actually made by a taiwanese company and sold under several brands) The matrix is a fine mask for those depths. The micromask beats the alien for visual field, volume and the nose pocket is larger - it also beats or matches the much larger matrix for visual field. Volume (which is not so critical above 20 meters or so) is so small that I once filled mine with water, cracking up at my dive buddy's reaction when I snuck up on him, cleared it and stayed down another 30 seconds. The alien has very soft silicone but a 'michael jackson' style nose pocket. The 'beaver' mask is very comfortable - not quite as good as the micromask for field of view to the sides but it is nice not to have a post dividing your eyes.

I use the micromask or a sphera most of the time. In my opinion the micromask is the best of the lot - provided it fits. It also does leave some fearsome lines in your face for a few hours. The sphera is an awesome mask, with unbeatable side and upward vision, but it is fragile, with polycarbonate lenses that scratch - and downward vision is poor, something you are apt to notice while wrangling fish in close.
