I have the Gaiam mat and like it a lot - especially being able to throw it in the washing machine. It has no padding at all, so I usually lay it over a public mat in a studio, or on carpet in a hotel room. The fabric top gives plenty of grip when my hands sweat, not so much when they're dry - but if you expect to have dry hands throughout your session, you can turn it sticky side up and it stays in place reasonably well.
