We use both VR and AR in the clinic (Rift & hololens), so my experience comes primarily from playing around with that. Tried using cellphone-driven headsets for watching movies while traveling but it was too unsocial for my tastes. I've tried out the Rift and the Vive but the game demos didn't really do anything for me. Some of the imnersive documentary type content (concerts, events, retelling of refugees' experiences, mountain climbing, flying, underwater exploration etc) were really compelling though.

My fave so far has been the Oculus Go and I'm thinking about buying that, but, again, it's kinda boring watching a movie while wearing a headset.
