I have two of the Quilters Select ruler 6x 24 and the 8 inch square one. They are not my go-to rulers though. Something about the frosted yellow color. Check the markings on the ruler. You can read it from any direction so you have to be mindful of the measurements.
I have yellow and green Olfa rulers and do use them. It really depends on the project and what I am cutting.
My go to rulers are the Creative Grids, 6.5 by 24.5 (also used to ruler fold fabric) and the 6.5 by 18.5 plus other sizes. I like that there are some black lines and white lines. Easy to see on light or dark fabrics. The marking lines are longer so line up easier for me.
Consider how you like to see the markings.
I will confess that the MSQC 5x15 jumped in my cart last week. I love it to ruler fold pieces that are less than a fat quarter. Perfect size!
So it's different rulers for different tasks in my sewing room.
PS: See how the pinky finger is on the edge of the ruler about 2:06 in the video? I started using this method as it helps hold the ruler in place.
