Yeah, the Quest's boundary setup process astounded me at how polished and user-friendly it is compared to the Vive and Index's room setup process.

Anyone saying that the Quest's software is obviously terrible lives on a different planet than me. The Quest is so simple and works so well, especially compared to other VR headsets+software I've used. I really like the Index too which I use a lot and think does some small things better, but I find it hard to deny the Quest is much more approachable and polished.

Quest 3 is my first and only VR device so I'm obviously not in the know in these matters, though I have to say I don't see what is so terrible about Quest's flavor of Android either.

For a regular user, most everything seems to work well. Setup was easy, UI is polished and simple enough to get out of your way, and I personally haven't encountered any show-stopping bugs with it. Maybe I don't expect much out of it, as I see it more of an entry-point to actual VR applications I want to use, rather than something I'm more invested in.

If anything, I was surprised how well it worked for a product still so early in its lifecycle.

It makes more sense when you realize some people have an extreme distaste for anything made by Facebook. If you want to dislike something bad enough, it's not hard to find/make up reasons to do so
