VRChat is free, so it is worth a shot to give it a try. VRChat actually does not require a VR Headset to play (though it definitely helps), so you can try it for yourself if you like.
VRChat does unfortunately suffer a lot of unsupervised children and other people who causes a nuisance being in public instances. So finding people to add to your friends list or finding groups to join private instance is the key to having a good experience.
My opinion on EAC is that it sucks, but there isn't a viable competitor platform that offers the same features and the large playerbase. I think that the program experience has gotten way better for me, due from the pressure to add proper features ever since there was massive backlash of EAC.
I unfortunately cannot comment on any other headset since I use an oculus headset as my primary PCVR headset
Yea I typically don't mind when it's a few people, unless I'm in a public instance and theres quite a lot of people in the world, then I have to start blocking very poor avatars to save my frames
