I think they are two very different solutions. Not just technically.
Append to the performer's body a piece of technology define your work
esthetically too. It defines another kind of interaction, between the
dancer and the environment or public and technology. It's not bad.
It's about what do you want. In my last work we decided to use just
camera tracking for example, in order to make evident the relationship
with camera surveillance system to the public. I'm not saying with
that I prefer camera. Depends witch kind of interaction do you want.

For something like this I'd use wiimotes.

You can also use two different cameras at same time if you really need
deep.And will be cheaper than kinect. But that also depend from the
kind of interaction you want. You don't really always need all this
data.
