I started with kbin but left it for lemmy + mastodon. It was not mature enough to handle so many users (which was unexpected by its own creator). Too many issues with bots, the instance itself, and the lack of mobile apps motivated me to move on. It’s sad because it’s creator seemed pretty invested into its project (and I loved the UI, and the ability to get both a Reddit-like and a Twitter-like experience).
If your main goal is to play games on PC, you should not buy a Meta Headset because you will have lags and artifacts by doing so (even with a cable). It’s more suitable for playing games from the Meta ecosystem.
I am not much aware of all PCVR options, I bought a Valve Index a few years ago and I do not feel the need to change it (though I admit I will likely buy the future Valve headset if they release one, but it’s not like I would buy it day one, just to get an upgrade).
