that's not really a fair comparison at all... the sixaxis is the better controller by a long shot, because it's the same proven comfortable shape and design we've been using for something like 10 years, with a few changes (some good: trigger/shoulder buttons, tilt function ((which is a great addition, like it or not)) some very bad: no rumble)... with rumble added (which i'd say is just a matter of time, given the backlash) it could rival the 360 as the best controller out there.
the wii-mote is the better motion sensor by leaps and bounds, but is still a freakishly stupid idea to base a console on, in my opinion. it should have (and probably could have) just been a peripheral for the gamebube, and i'd bet money that that's how the idea for it started out.
