Well, I don't know about more impressive results :-) but it sure is a whole lot easier for me. The motion is more natural, as you are moving the pencil rather than holding the pencil stationary and moving the paper, if that makes sense.
It's much quicker to load a quilt on the frame compared with preparing the quilt sandwich. I also think it's easier to get the backing loaded smoothly.
In general I find the process quicker, especially when doing utility quilting such as loops or a meander.
