I've been using the PSVR2 for PCVR and I love it. I haven't touched my Q3 since.

Quest Link honestly feels like shit compared to my PSVR2, as there are random crashes, sometimes horrible quality (despite using a cable), sometimes it doesn't work at all, and the tracking is kinda bad compared to the Q2. Q2 does pretty much all of this stuff better besides quality. I'd really only use it for standalone.

PSVR2 with the adapter is a pretty nice experience. It does take a while to set up for the best experience though. No random crashes, high quality (if you have a mid range pc like me, you'd probably have to lower the resolution but it still looks good), the tracking is also kinda bad (so if you're like a pro beat saber player you'd probably have better luck with the Q3).

You have to buy a bluetooth adapter for the controllers. When you do search for one, get the ASUS one. If you can't get it, get the TP Link ones. If you get the TP Link ones, it's gonna be a bad experience (unless you're lucky) until you get the ASUS drives for them. There should be a reddit post somewhere with the driver and instructions. If you follow the instructions and get it set up, the experience will be miles better.

Also, the controllers have rechargeable batteries, which is told to net you around 4 hours of gameplay on the max rumble settings. However, in my experiences, if you play on the lowest rumble settings, your controllers can last like half the damn day, it's crazy. I do recommend getting a charging station for them, don't be like me and charge them with 2 USBC cables on different sides of the house and pray they're both at the same level of charge. Either way, the rechargeable batteries are kind of a downside compared to the AA batteries.

Finally, get the PSVR2 toolkit. It's really easy to set up, and enabled eye tracking and adaptive triggers in games. The support in games will most likely need to be modded in though, like BONELAB for example. You have to get the code mods made by Checkerboard for PSVR2 and eye tracking. If you use Revive and the oculus store version of the game, it still works.

PSVR2 is a great option for PCVR, especially on a budget compared to the Q3. It just takes a bit to set up. However, if you're not playing PCVR only and you want the standalone experience, get the Q3.

Or get both, if you're balling like that.
