The CV1 sucks.
I'd take an Oculus Quest + Oculus Link, Vive Pro, Valve Index and Rift S over the CV1.
The Quest + Link is a bit of a stretch but I have a lot of faith it'll look nicer than CV1 and the tracking on my quest has left me very happy after the updates. Big deal breaker would be refresh rate but I'd take the extra clarity and the beautiful screen of the Quest (every CV1 screen I saw was horrible).
The Rift is a clear upgrade in clarity and a downgrade in sound. The only issue with it is no adjustible IPD.
The Index is another clear upgrade in clarity, FOV, sound, refresh rate but a downgrade in software and blacks.
The Vive Pro is just an upgrade in resolution whilst maintaining blacks and giving access to wireless if you like that.
Its a good time to be in VR. Lots of choice. Bang for buck, the Quest or Rift S are clear winners. Longevity wise, its clearly the Index. The Vive Pro is basically a dying breed of OLED headset which, if I owned, I probably wouldn't give up on. Its main negative is the disgusting controllers.
No matter which headset you choose, I think its an upgrade from CV1. The big miss from CV1 is clearly the controllers which I personally think are best-in-class. Just ergonimcally perfect, felt premium, perfectly weighted, button placement perfect, haptics great... I think they'll go down in VR history as the best controller of all time or one of them.
