While I agree it’s the better headset, the $800 price difference and the requirement for an attached gaming computer, make it easy to see why the Quest gets the attention it does.
The closest thing I’ve found to an in-between is the Pico 4 at ~$450 and doesn’t require any accounts. The game library is quite limited, so it’s not a full replacement for the Quest, but it can connect wired or wireless to a dedicated PC. Newegg seems to be the best US supplier for them.
