I use both. Depends on how small and how accurate the pieces need to be. Sometimes the ruler just does better. The lines on a ruler are narrower and maybe make for better accuracy when cutting some pieces. But, let's face it, some of Jenny's techniques stink! She irons, not presses. She uses techniques that leave bias edges. However! The things she is demonstrating are not intricate or demanding of perfection that some patterns require. She is marketing her precuts and does things that work well with those and are fast and easy. Usually seams don't have to meet exactly like some designs do. She is having fun with what she does and is trying to spread that enthusiasm. I would not recommend her methods for the beginning quilter since she does "cut corners' on techniques. A more experienced quilter knows when to do that and when to do better. (Have you noticed she doesn't have a video on how to remove stitches? Most of her designs are pretty forgiving.)
