I like Dean Dills Pad, you're not going to be able to carry it around if your strolling but its a beautiful pad to work on, great for Matrix. I personally don't ever use a pad when I'm working, I'm usually working out of my pockets and make do with whatever space I have available to me.
I have a Sterling and a Gibson. Of the two, I prefer the Gibson, although the Sterling pad does come in a nice casino table green. The Gibson has a velvet surface. The Sterling is more like a felt surface. The Sterling feels little sturdier, but both of them are wearing well.
I too use the Card Worker and it's the best surface I've ever used, and I've owned at least 20 pads in the last 15 years. The card table green is just muted enough so it doesn't appear like a pool table glaring green. Very nice! It's also the perfect size for cup routines & you can actually spread an entire deck.
I'm getting another one to mount to a nice piece of stained walnut that I can use with my nice waiter folding table. Then my wife can have the dining room table back...
