I am a huge fan of Creative Grids. They have built in grippers to help keep the fabric steady as you cut. I had the flouresent green and yellow rulers and but made way too many cutting errors. I like be able to view my fabric and find the Creative Grids cuts very accurately. I know that they are a bit more expensive but are certainly worth the extra cost. I was fortunate to have been gifted several new ones this year and have been selling some of my older ones. I have two 6.5"x 24.5" left, pm if interested.
