Matrix is terrific. I've "converted" some friends from Signal to Riot and we're not going back. Video/calls and group chats work a lot better, and the riot.im web client is excellent (at least, compared to Signals lack of).

I've also stopped using an IRC client and just use a Matrix bridge. Really happy so far.

Main drawback is that E2E is a bit clunky to set up, and downright confusing for non-technical users.
