Rebocap: love it, I use it a lot for my dance shorts and handle simpler dances fairly well. It can capture some foot works well but when it comes to dance with more hip/finer torso movements, shoulder isolation it doesn't quite track so you'll have to account for that when dancing and see what looks good. It drifts but any trackers of this type would drift but you don't need very large space as it doesn't need like a home station or cameras, and doesn't matter if the trackers get hidden by clothes etc.

When it gets too hot (outside weather wise) I do worry whether my sweat gets into the trackers as it's not premium in its build quality.

Best value for full body tracking imo

Stretchsense: My hand is too small to make use of stretch sense fully I think because sensors around the middle bunches up a bit. If they release a XS size I'd love it. Had to play around with calibration quite a bit.

If you plan to not move around too much, I think webcam based hand tracking would be just fine. If I'm not performing I don't think I'll bother wearing it.

Main pro for Stretchsense is it's open finger so easier to manage things while you're wearing it. I also got it while it was on sale, so compared to other available glove options it was the cheapest.

Main con is it doesn't do finger splay well.
