I have the Olfa because that was the best on the market when I started quilting. I do love it but if it was not so expensive to change, I would like to try the True Cut ones. I think that is the name of the ergonomically shaped cutter and rulers that have a ridge on the ruler edge that the cutter runs along. I think it would be easier to control. If you are just starting to build your supplies, try out a few to see what you like.
