I won't be knocking you for using Razer, some of the hate is very overblown. That said I choose not to use their current range of peripherals because of the requirement to have the software installed (no memory on the devices.) I've had as many mouse fails with other brands inc. Logitech, and some Razer mousepads are excellent. I haven't had the pleasure of Artisan's mousepads, but I've tried numerous others and first generation (which hasn't frayed) Goliathus Control is my all time favorite pad.
I've got a couple of Gamdias mats that are supposed to be copies of the Control, but neither of those lay flat, I mean to try trimming the edges myself at some point. I've had others pass through my possession, a Corepad for sure. I can't remember all of them, but it also seems to be a never ending source of complaint on the forums like OCN and ESR.
Although there are other issues with different pads, various non-stitched Razer, Roccat, Puretrak, Mionix, Steelseries etc have all layed flat just fine when I've had them.
