I've been using my Quest 2 quite a bit lately as it serves as a nice workout device. My game of choice lately has been Synth Riders mostly due to my BMBF install refusing to add songs to Beat Saber. (Note, I am on the correct version; it just doesn't ever download the songs when syncing my list with BSaber.) The advantage to Synth Riders is that it supports custom songs by default, so there's no worries about updates breaking support! However, the game does have far, far less custom songs, but given Beat Saber's popularity, that is not surprising. The games are both musical rhythm games, but they really aren't too similar after that point.
I did also try out Ragnarock, but I find that it'll take quite some time to get used to attempting to hammer on stationary drums while focusing on the note lanes.
I've also got a few other games that I need to try out such as Swarm and Yuki.
I'm intrigued but I'm out on facebook. Is that basically the only good option right now?
In its price point, yes. The problem is that most PC-only solutions start at $500, and they're tethered by default. (You can often get a wireless adapter, but that's usually another $250 or more.) I'd argue that the biggest advantage of Valve's SteamVR outside-in tracking (i.e. uses external IR emitters to allow a device to determine its location) is that it provides better tracking overall. The Quest and other inside-out tracking devices (i.e. uses cameras on the device to determine the location and the gyro to approximate if they move out of view) can be a bit of a mixed bag with this approach, but I believe the consensus is that the Quest has the best inside-out tracking. (The biggest issue that I hear with other inside-out HMDs is that the controller tracking can be finicky.)
In my time with VR, I've used a Vive (SteamVR), Vive Pro (SteamVR), Odyssey (WMR), Quest (Oculus), and Quest 2 (Oculus). The two that I would recommend out of that list would be the Vive Pro or the Quest 2. (I'd like to try the Index at some point to see if I like it better than the Vive Pro.) Where I think the Vive Pro outright destroys the Quest 2 -- ignoring the required Facebook integration of the latter -- is fit and finish. It's pretty obvious that Facebook/Oculus did a lot to bring the price down on the Quest 2 (it costs $100 less than the original), and one area where this is the worse is with the default strap. There's no way to mince words on this... it's an awful strap, and you pretty much need to spend another $50 just to get something good. (I use a Deluxe Audio Strap from my original Vive with 3D-printed adapters and Logitech IEMs for audio.) The Quest 2 also only supports 3 IPD settings, which are "selected" by physically moving the lenses. This is slightly problematic for me, because the Quest 2's maximum IPD is 68 and my IPD is 71. So, I always feel a little cross-eyed while using it.
Ultimately, the biggest benefit of the Quest 2 is its price. It's quite a bundle for $300, and especially now that the base unit has 128GB of storage. (Prior to the unit being pulled due to a recall, the base Quest 2 had 64GB.) The ability to take it anywhere is nice if you want to travel around, show it to friends, etc. You can also still stream VR games from your PC via Oculus (free) or Virtual Desktop (not free) either wired or wireless.
Overall, I'd recommend the Quest 2, but just make sure to grab an aftermarket strap to use. Also, if you do decide to use it, find someone that already owns one to refer you. I believe the promotion is still in effect, but last I checked, if you refer someone and they buy a quest,
BOTH of you get $30 in Oculus Store credit. Essentially, you get a free game of your choosing. Oculus also gives out a decent amount of targeted 30% off coupons. Outside of that, their deals aren't up to par compared to stores like Steam. Although, some games do support cross-buy, so if you can get the Oculus PC version, you get the Quest version for free.
