In my opinion, depends on if you want to be involved with roleplay.
Beware is monsters and magic, Gor and Jag is Masters, Mistresses and slaves. I believe @gor are more people who live it realtime. Jag is more roleplayers.
Soi is just everything.
Bwr, Gor, and Jag you will probably get some flack for making a room that doesn't "fit"
I have had people whisper to me in beware when I was roleplaying in my room that they didn't like my roleplay. Halloween stuff a couple of days before Halloween. I just told them to feel free to put me on ignore.
