I have Wii Fit Plus and EA Sports Active (the first one, not 2). I like both, but I felt like I got a much better workout with EA Sports. A bit more variety and ability to personalize routines (you can't set up your own routine with Wii Fit that includes games or aerobics, only yoga and strength training). I also like the 30 day challenge that gives you set workouts that are balanced and gradually get more challenging. I don't have any experience with the My Shape, but have heard positive things about it. I think either of the 3 would be good, but personally I'd choose EA Sports Active 2.
