There's a real mixture of reviews on the rain forest. Some glowing some really negative, I had one in my basket last night but now I'm thinking I should wait for the quest 3. I was even toying with the idea of the quest pro seeing as thats had a nice price cut and I was looking at buying a good used one but still unsure. I've been using my sons quest 2 all day yesterday and while my opinion of it has improved I really don't like having to unplug it to recharge it, wireless is ok but I can see compression artifacts slightly, even plugged in the bitrate feels lower than my Rift S due to the DP port instead of usb.
There does seem to be a substantial difference somehow between how the Quest 2 performs wirelessly and how the Quest Pro does. It's not just sharper, it also seems to suffer less from compression artefacts. They are there, but nowhere near as noticable.
I'm not sure why that is - possibly it's due to the panels which are better at hiding it (I had a cheap TN monitor once that showed up every bit of video compression, but a more expensive IPS one didn't), or the SOC can handle the thoughput better, but it is a noticable improvement, and it's much better over a cable too.
It does depend on the game though. Most games look great wireless, but a few like Skyrim and driving sims tend to show compression more and benefit from a wired connection.
I used to use my Index in preference to the Quest 2 for PCVR precisely because the Index looked sharper despite the lower resolution.
Quest Pro looks way better than either the Quest 2 or Index. It's the first headset I've used that can replace both for each use case, wireless and wired.
Quest Pro should support Wifi 6E in a future update which hopefully will improve wireless quality. Quest 3 should hopefully be better than the Quest 2 for wireless, maybe better than the Pro, though that remains to be seen.
Basically, wireless PC VR is getting better with newer headsets, and will be much better when the new wireless standards are supported.
