I had the Quest 2 a while ago and did manage to play some games on it (PCVR through Virtual Desktop, cause they didn't have 1st party support for Intel Arc B580).
In regards to shooting games, while some of them were nice (especially modded H3VR, all of the guns you could build etc.), the shooting and movement always felt off - rounds not always going where you'd think they should regardless of the game, aiming being a bit clunky especially with scopes and so on, same with some RPG combat games. I also tried out Into the Radius VR, CONVRGENCE, SUPERHOT VR and Zero Caliber VR. There was something weird going on, like the world scale feeling off and even when adjusting through the SteamVR options, the experience still being odd, no matter what IPD or height offsets or other settings I'd try. Never really got used to it.
But let me tell you, vehicle games were on another level. It's perhaps the best way to fly in War Thunder because the proper depth perception completely changes the feel of it (if they'd fix the damn camera, I don't want to break my neck trying to look far back), same with VTOL VR and racing games like Dirt Rally and even Euro Truck Simulator 2. You'd think I'd get motion sickness or something but no, it just felt good and more proper than staring at a flat screen, despite the limited resolution and all else. Oh and oddly enough Derail Valley also felt nicer than the FPS games, despite you also moving around a bunch (though it's mostly a train game).
VR is definitely a cool novelty, if sadly underpopulated. There was also some cool productivity software like Immersed but they kinda ruined it by removing support for multiple physical monitors and also the Virtual Desktop program and SteamVR won't let you display like 4x1080p monitors all at the same time, what's even the point of being limited to just one or two in VR? You have 360 degrees around you (well, or however much your neck can comfortably do)!
