my 2 cents,
Hope to not say something wrong since I test three differents prototypes of Asus XTION 2 last year.
While Xtion was just a kinect/primesens (structured light) camera built by ASUS (i.e. they bought the IP and a “Calibration machine” to recompute the disparity lookup since dimension was not exactly the same than the Kinect/Primesens).
On the other hand, XTION 2 is a ToF camera so it’s not really comparable (pro & cons), if I remember well XTION 2 seems close to old softkinetics ToF cameras DS400 DS325 etc…
note: Asus also had a “RealSense” camera (first generation, "un"structured light) as “prototype”, but it seems Intel has decided to discontinue it and the new RealSense has been developped by an other israel company with a completely different technology (ToF)
