I think cutting mats are like our other tools...mostly personal preference. I am on my second Olfa mat and have no issues with them. Actually, have one of their rotating mats as well. Probably because I use the same spots all the time that one seems to be showing a bit of wear. But the large ones I've had seem to hold up pretty well. Took me about 10 years to wear out both sides of my last one.
But the gingher one mentioned above is intriguing...will have to check that out.
