I have the Olfa green one and have been very pleased with it. I have to use the plain side. I use rulers for my measuring and my ADD brain can't handle two sets of lines and numbers. When it seemed a little rough, I just washed it with a cloth and spray cleaner and it was smooth again. I have the gray Fiskars here and at church. I do not care for them. The same blade is much harder to use on either one of them than on the OLfa.
