I use a Fiskars mat here at home. Grey with yellow lines. And I have a Fiskars cutter, too.
But at the shop we have Olfa and use Olfa cutters as well. I like both brands and have no trouble switching back and forth.
I refuse to use anything other than Creative Grids rulers. They are the best...lines marked well, 1/8" increments, built-in grippers on the back, and very accurate.
