@riverpunk@defcon.social I just switched to XMPP using Snikket. My biggest ask was reliability, because we were having a number of issues with Nextcloud Talk, and so far XMPP has been super reliable. I had asked people on Lemmy about a reliable service, so you can check out that thread if you want, though it's more focused on self hosting: https://lemmy.world/post/49675638
