Steelseries SX is absolutely the best mouse pad I have ever experienced. It's an aluminium one with fiber polished hard anodised surface. Had mine quite many years now and there are no signs of surface wear. It's very slippery, quiet and all my mice glide (and track) beautifully on it, optical and laser.
Two downsides, though. You have to make sure it stays clean. Hard grit on the surface will get cught up by the mouse feet and end up wearing the surface. It's easy enough to notice when you get some, though. You can both hear and feel it. The other downside is it feels cold for a while where your hand touches unless you're in a really warm room.
My second favourite is a hard plastic one, the S&S. It's my portable mat and stands up to a lot of abuse. It's tough and a little rougher than the SX (not as smooth glide), but the surface has also lasted a good long time without much change in the feel or glide. It's more tolerant of dust and grit.
I haven't tried a glass pad, but I heard some mice (with laser sensors mostly it seems) don't track well on them.
