I have the Grace hoop on a stand, because I was looking for something that would let me quilt in the living room. Before I bought it, I read reviews on line and almost every review was positive. However, I do not care for it much.
It doesn't hold the tension well in the corners, and I found it hard to adjust. However, you have to realize that I usually use a floor frame, so I think my experience is not quite the same as others, and maybe I didn't really give it much of a chance.
I will say that Hinterberg is a great company to deal with, if you go that route. I bought my floor frame from them 20 years ago, and they recently sent me wing nuts to replace one that broke. I know they were recently bought by someone, so I hope they still stand by their products.
