I started with clear on the theory that letting more light in would be good, but now I use a black skirted mask almost exclusively. I agree with some of the others that the clear skirt can be distracting. Side windows (like the Liberator) are even worse. If you get a nice low-profile mask (and I think the Big Eyes should qualify) you will be able to see well enough you really won't notice the skirt much at all. But I still have my old clear-skirt masks (one identical to my black one) to use as back-ups and I wouldn't hesitate to use them for any dive.
