Quest uses inside-out tracking (cameras on the device to perform feature-detection and SLAM) to give full 6dof headset and controller tracking. The GearVR and other current stand alone headsets only track rotation via gyroscope, which is much more limited

Thanks (and thanks to Mindwipe as well) for the answer - I'm only just dipping my toes in VR at this point!

Also Quest has a custom cooling solution with fans, that makes a large difference.

Slotting in a smartphone doesn't have cooling optimised for this kind of use case at all.

That was the Oculus Go. The Quest is slightly higher end in tracking and having 6DOF, but lower end than a full Rift setup.
