Using a mixed reality headset for VR, instead of a dedicated

There's a lot of potential for Microsoft Mixed Reality, like being able to see a sinkhole form in the middle of your floor or seeing your wall open up to an alien landscape. A lot of the Steam VR games support Microsoft Mixed Reality as well as VR headsets (but they're just plain old VR games and don't make use of mixed reality features). How does using a Mixed Reality headset for VR games compare to a dedicated VR headset?

Any help appreciated.

I didn't find the right solution from the Internet.
