Played 'em all. I own WM+ and Kinect.
Functionality:
1. (Tie)Move and Wii Motion Plus
3. Kinect
Kinect has some really cool features but it spazzes out sometimes. WiiM+ and Move are super precise.
Games:
1. Kinect
2. Wii Motion Plus.
3. Move
Move comes in last soley because of a lack of "Move only" titles. It lacks that one must own title to justify its existence. Wii has Zelda and Kinect has Dance Central. Kinect has a wealth of titles and most are Kinect only. Wii wins on the strength of Skyward Sword.
Overall:
1. Kinect
2. Wii Motion Plus
3. Move
While move works very well, it's no game changer. You can have a full PS3 experience without ever touching a Move. Wii Motion Plus has Zelda and a few other games that live up to the promise that Wii made back in 2006. As for Kinect--I had(and still have) a house full of visitors for Christmas. Two 20-something guys, Two 20-something girls, an 11 year old boy, my ten year old daughter, and my GF. For the last few nights, my living room looked like a Kinect commercial. I can honestly say that the last few days have been some of the most awesome social gaming I've ever had. Kinect is a winner.
