I've never hosted my own jitsi instance, but I use it quite frequently for a variety of purposes both personal and professional. It is, in my opinion, the best of all the conference systems out there, FLOSS or otherwise.

Every other solution has consistent technical problems for me, worse hurdles for adoption (with jitsi, I just send a link to friends, nothing to download or install), significant dark patterns, or awful performance. Jitsi has none of that, and on top of it, is privacy-respecting and focused on the public good.

All the best,
