I agree. For a period a several years ago I was tasked to oversee this in a museum alongside an occulus rift early dev kit and some other tech curiosities. The leap motion almost never worked, and people would usually end up disappointed. The kinect seemed to achieve everything it was trying to do but better and for the whole body.

The occulus rift dev kit comparatively despite being a prototype, stood up amazingly well to the general public, even if I didn't feel it was that impressive, it was awesome to give the first view of VR to so many members of the public.
