I have Creative Grids, Omni Grid, and Quilter's select, plus an ancient Olipfa. I hate the Omni Grid ones - the fluorescent green/yellow gives me eye strain and headaches. I wasn't that fond of the Quilter's Select overall "haze" and felt I had a harder time seeing many fabrics' edges through them, unlike the other brands' clear plastic.. I've been using the Creative Grids ones for a couple of months now and absolutely love them - so much so that I've since purchased several additional sizes.
