I don't know about significantly better, but it's different, and those differences might make for a better or worse experience depending on the type of game. Perhaps one improvement might be independent detection of rotation vs panning of the camera, distinguishing between those, which I don't think the wiimote pointer output provides for. The other big difference I guess is just the different relationship between controller and screen in each case...in the pointer case there's a strong relationship, it's like a lightgun, in the case of that sixsense stuff, there's no relationship really, it's abstracted away a bit. I don't think that's better or worse or whatever, I think that is totally dependent on what suits a game.
