I used to own a quest 2 and would use it exclusivly for PCVR. The big thing that made me sell it was all the problems that come with streaming games from another computer:
There is more delay in the video stream than quest-native games
The video looks like a youtube video since it's being compressed
Wifi is very unreliable. Even with a dedicated AP just for the quest, the stream sometimes dropped frames.
For these reasons, as well as all the bullshit that comes with a Meta product, I got an og HTC vive instead. I do miss how convenient the quest was though.
I have a Quest 3, mainly play PCVR via VD. It's not perfect, but it's pretty damn good. I don't really notice much, if any delay, and the streaming quality itself is largely dependant on your settings and router capabilities, for me it's sometimes noticeable but definitely not enough to put me off it.
I got a quest 3 for steam vr and using the link cable connected to a usb 3 I like it
The battery still does drain but super slow and usually lasts me a full long play session (sorry my sense of time is shit)
I got mine because my laptop has limited ports and the quest checked my boxes
I use virtual desktop when I play wirelessly but I really use it rarely because like the other guys said it’s like a YouTube video, so I use a cable
Btw Kiwi is a excellent brand if you go for a quest I have their controller straps, the Head strap, and the Link cable which has this little cheap plastic piece to move where the cable drops from the side of your face to the side of the strap
I love them way better than the metas overpriced stuff so if you get a quest i recommend those
