What is the best HMD right now? Samsung Odyssey?
Vive - limited resolution , bad lenses , bad head strap so so controllers
Best tracking with light houses , premium head strap , vive pro for great resolution
Rift - same resolution as the vive , sensors need usb and you need more to equal vive tracking
Best controllers , head strap is as good or better than the premium vive. Some great exclusive games
Odessey Plus - Controllers are so so , tracking is not as great as the other options
Best resolution (the same as the vive pro + anti sde tech) no external sensors
The rift and OP can be had for $350 the majority of the time.
PS VR - lowest resolution , poor tracking , move controllers
Lowest cost , RGB so sde is not as noticeable , can only play ps vr games .
That is the best summary I can give you . I have a rift and OP . I use my op more than my rift now. I do this because set up is a lot easier and the higher resolution and bigger (its like 10degrees bigger) fov makes a drastic difference for me. However I will freely admit the tracking is not as good as a 3 or 4 camera rift tracking and the controllers are lacking compared to the rift. Facebook should have put out a rift 2 with the same specs as the upcoming Quest. It would have put it on par with the OP but with better controls . As it is now that resolution is really hurting the vive and the rift.
