I use it, but feel like XMPP is dated and complicated. All the extensions and whatnot are awkward to get setup and you can't make assumptions about how well they're implemented or built on the server you're on or communicating with. I intend to move to matrix/riot when it gets more stable. Things like video are second class citizens on XMPP too and the desktop apps are painful in my experience.

I definitely wouldn't suggest it for video, but I've never had an interest in video conferencing in general. Extensions are pretty straight forward in my experience - either your server supports them or it doesn't, but most of the time they only impact client-to-server in this case rather than server-to-server.
