You're wrong.
FB is focusing on an all-encompassing experience. Look at their evolution, well - sort of their evolution. Where it started and where it is.
From the DK1 to the Quest 2. Quite the testament to an ever evolving product.
My first VR headset was this back in 1996

We have come a long way in a very short time considering the massive hiatus in the technology from the VFX1 days to the DK1.
Having had the DK1, DK2, CV1, Rift S, Quest, Deepoon, Vive, Pimax and a few other niche headsets along the way, I can honestly say it's all well and good throwing numbers around and comparing apples with pears, the proof is in the actual experience though.
Best review of something is actually trying it for yourself.
You keep blabbering on about PCVR but you miss the point that the Quest 1 and Quest 2 are very much PCVR capable and extremely proficient at it. The Quest 2 is a replacement for the Rift products. There will be no further development on the antiquated way of doing it from FB.
It good news.
If you're chasing numbers though and giving up on the actual experience of it before trying it - then perhaps you're right, it may not be for you and sticking with what you think you know would probably be best.
