For me frameless masks way to go. I have Hollis M4, bought it like 4-5 years ago and still in perfect condition, I use same as back up as well. However mask is pretty personal thing that a mask works perfect on some people might not work for other at all.
I have a buddy literally bought and tried three quarter of the masks available in the market and still unhappy.
