I tried Quest's Air Link yesterday and figured it's worth sharing with everyone:

Virtual Desktop is still my preferred way to play PCVR games with Quest 2. Air Link and cable Link seem to have strong aliasing and slightly washed out colors compared with VD. Cable Link also uses the most GPU. 

VD also has a nice desktop view which is rendered within a native quest environment and looks super sharp and the colors vibrant. 

Wireless PCVR on Quest 2 with FBT hybrid setup is probably the best setup rn, depending on your exact needs. Quest 2 is the best VR to recommend to anyone right now, casual or hardcore. Index is way more expensive, and while it has higher FOV and better image quality (for PC), the controllers suck and I also can't be doing with RMAs. And it's wired vs wireless. And it doesn't have optional standalone. Being able to use Quest in a car or when visiting family is awesome, even if just to watch content on a big virtual screen in a comfy virtual lounge.

I do hope HTC somehow pull something magical out of their ass since I'd like to have a proper quality PCVR headset but I have no faith in them (I want much larger FOV and non-compressed image quality)
