From my own experience, I will not recommend for kinect exercise game. The Wii is much more for the purpose of gimmick. But I don’t know how you want to utilize it. It is your own personal choice. But I have seen that most people love to use the second one. That is the reason for me to recommend it. Along with exercising if you want to do some coding, as you are a coder, then xbox360 with kinect.
