Can concur. I'm running a pair of D435 under Linux. Still some teething issues, see the SDK and issues at [0], but the quality of the data out of these things is amazing compared to previous generation sensors.
Looking for something comparable to the raw resolution of the iPhone X camera (which is a descendant of the old Kinect camera). Mainly older cameras on the market: https://stimulant.com/depth-sensor-shootout-2/
On iOS, Apple won't let apps access the raw depth sensor data, only a reduced-resolution sample.
