I would suggest going for kenict xbox one (2.0) as they provide a much wider field view and provider more skeleton points than 360 kinect.
But do keep in mind that you’ll need to use an adapter to connect it to the PC
I was lucky enough to buy a used kenict xbox one for 40$ and PC adapter for 23$
This kind fella explain the differnce between 360 kenict vs xbox one kencit
Kinect V1 Vs Kinect V2
