Touch mouse for windows 8

Microsoft, logitech and others have started to make touch mouses for windows 8 to make gestures and the OS just easier to use. Some look finicky, and others look ok. How would a touch mouse compare to a gaming mouse, because i'm thinking of getting a new mouse, and I can't decide. Would you use one, and how do you think they will work? Do you think they would work like a desktop touchpad? Should I get one over a gaming mouse?
