This is one of those posts that will apply to a very small portion of the board, but those that it does, will mightly appreciate it.
I've been using the Mares X-Vision mask, mostly for the huge angle of view.
However, my face is just narrow enough that after a couple days diving, the skirt gets loose at the sides and leaks. You know, the slow trickle of annoyance. I'm not sure if it's skirt stretch or the frame is bending.
To compensate, I crank down on the strap until the mask center frame becomes painful, because it digs into the space between my eyes. It used to get so bad I'd consider not diving (!!!!).
Sound like you? I've just switched to the Atomic SubFrame. All the vision (at least so close I can't tell the difference) with a narrower fit. A fit I used to dream of, and quite comfortable.
All the best, James
