Graphically the native-quest stuff is relatively basic to run well on the hardware but for the kinds of things I enjoy most it doesn’t really matter/bother me. I use Virtual Desktops for PCVR on the quest 2 and in some cases I think the fancier graphics are worse. I prefer best saber natively on the quest because it has way less effects that reduce readability.
They are also using/pitching ASW as a method to effectively double frame rate so they can up the fidelity and maintain a high frame rate. I haven’t played anything that does this yet as far as I know but I’m a little skeptical on this technique.
It is pretty convenient to get going, at least for onboard apps - I haven't tried the PCVR support. You pretty much just put it on and you're off and running.
To me it seems for those who are nearsighted, wouldn't need glasses as the screen is very close to your face.
It depends somewhat on what you're doing whether this poses a significant problem, I suppose, but I have found the experience more enjoyable for being able to see it without having to fuss with fitting my glasses under the headset.
I got one for the boy a year ago (last christmas present) and while he uses it a lot I use it more connected to my PC for elite dangerous etc.
The extra resolution over the Rift S I had/have is well worth it (text is readable on ship displays on the Quest 2, not on the Rift S) - for the price they are an excellent bit of kit.
You often need 2-4x more panel resolution than the effective resolution to the viewer, just to deal with those factors (though this does vary wildly with lens and panel design).
