VRChat and RecRoom both are arguably "metaverses" (although we just called it "social VR" pre-hype) and have pretty healthy usage numbers. The latter is more of a games hub but all these apps are a mix of different use-cases so not a clear distinction. (Consider Fortnite which is now social but was originally just a multiplayer game)
There's a debate to be had about aesthetics - some of that boils down to taste. But you can't argue that all social VR apps are useless.

That isn't terribly clear to me at all. "How bad" in what way? What is "the whole thing"? The links you provided are comparing two apps. I presume you prefer one to the other. I'm guessing the reason is visual..? But I'm not sure.
I was actually hoping for some more clarity from you.
