I can't directly compare quality as I've not used Realsense devices, but the main difference is that the OAK-D uses stereoscopy without IR. I've been playing with it in various light conditions and it's surprisingly robust in low light as long as features are visible in both cameras. It only requires 1 USB-C cable if you're using it over USB3(i.e. a device that can source >1A iirc). I use it with a Jetson Nano(albeit not to its full capacity-yet) with just the USB.
