I have a Grace lap hoop as I want to sit on the sofa and don't want to lean over a floor hoop. I love the fact that it rotates on a ball and I can tip it any direction. The hardware adjustments are easy to make, and it feels very sturdy. However, I am not quilting a large quilt, only a small Hawaiian wall hanging. If you are doing a larger quilt, I would want the largest hoop size.
