(NOTE: I'm not saying I like the Quest 2 more than the Index. That isn't the case. The Index is an amazing system and the best VR experience I've had. I'm just saying I use the Quest 2 more often due to convenience, so, for me, it has its place.)
My Quest 2 has really grown on me and I'd buy a Quest 3 without any hesitation. Having said that, I only use the Quest 2 to play single-player games. I have no interest in online multiplayer games nor in VRChat. If those features are important to you, perhaps the Quest 2 isn't a good option.
The Room VR
Myst
Death: Unchained
Until You Fall
Tales From the Galaxy’s Edge
The third Vader Immortal (the Dojo part and not the actual game though)
The Walking Dead game is OK, but there’s too much wandering around and returning to the school bus for my taste.

So what gives? Why do users in your circle regret it? And where does the vr community hang out, so I can learn more?
The other obstacle is full body tracking. Turns out this just works much better if you have lighthouses to begin with, plus a headset that uses them.
As a current Index and former Vive Pro, I can tell you that my Quest 2 has the most game time because of one thing: wireless. The other issue is Steam VR doesn’t have nearly as many people on multiplayer.
VR Chat is interesting, but most people in VR don’t spend a good portion of their time there.
Only VR Chat and one game take advantage of full body tracking. I wouldn’t focus to much on it.
