Hello. As promised, I checked out chilloutVR. There are some things I liked about it and some things I did not. 
I've uploaded some videos. The first video will leave you with a pretty negative impression, the fbt calibration SUCKS. It took me a long time to figure out how to trick it into calibrating in a way in which I was halfway okay with. Then I join a public world, which kinda sucks. Then I join the meetup and play with the camera, which is actually pretty neat.
The interface is okay in some ways but not okay in others. It's pretty rough but overall I think it's more visually pleasing than vrc's current interface, which I do not like. I like that there are a lot of advanced user options in the interface but it does need to be fleshed out a lot. 
Oh, one thing I really did like was how it handles joining a new world. You don't leave the world you're currently in until you've already downloaded the next one. Very nice. 
Streamable has a 250mb upload limit now (which sucks) so I'm using unlisted youtube for hosting. If anyone knows anything better lemme know. I'll probably delete these videos in a few days so watch while you can.

Overall, I think it's very rough and it doesn't have a lot of the nice quality of life features that vrchat has.
It's something to keep an eye on but I don't know about moving over with it as a my primary game. I'm in the camp where I think we should do whatever is best for the community without being partial to one game or the other.
I think it's worth it to check out chilloutVR to see if you like it, but in my opinion it's too rough right now. Might be nice to visit but I wouldn't want to live there.
