For me, I had some trouble clearing my mask during my confined pool dives. I tend to inhale through my nose . So for me, a mask with a purge valve really gives me a sense of calm to know that I won't inhale water when clearing my mask. That said, I use a great defogger and have never had to clear my mask apart from when I was doing my skills . Then again, my instructor friend swears by simple masks (no gadgets or valves) as he believes that the more pieces/gadget you have, the higher the chances something will fail!
