I have Olfa mats, a friend of mine just bought me an Omnigrid mat, and I absolutely Hate it. I don't want to hurt her feelings though, so I still have it on my cutting table, just on the other side of where I usually cut.

I've read/heard that the Martelli mats, you can only use Their blades, and I've tried their cutters and don't like them. Regardless, I wouldn't buy them, because I like all purpose. To me, you have a mat, you should be able to use any rotary cutter on it.
