The vive is absolutely not reliable, but still worth it if you can pick it up cheap second-hand. Index is the best headset on the market right now, though ymmv with the controllers. It's still using the lighthouse tracking, so you can set up fbt without fuss.
Rift S is cheaper, and cuts a few corners, but it's a decent headset to start out with. Makes it easier to play the Oculus exclusives.
