What I like about the lap hoop is that it is easy to move and easy to store. At the moment it is sitting on the top of a bookshelf, out of the way and not taking up any floor space. I was never tempted by a floor hoop because it takes up more space. Also, I tend to be clumsy and I really did not want to be tripping over it, or having to stretch at awkward angles to move it out of the way.
Reasons I can think of to buy a floor hoop instead of a lap hoop: (1) you get too hot with a quilt in your lap and over your legs, (2) the weight of a quilt in your lap makes you uncomfortable, (3) you have back or neck problems which might possibly require you to work at a higher distance from your lap. I have worked on a PVC floor frame and found that to be really, really hard on my back. However, the lap hoop does not strain my back at all and is very comfortable to use.
So, for me anyway, a lap hoop is probably preferable to a floor hoop.
