Your experience seems to mirror my own. I still use matrix very little, but have defaulted to use xmpp. Well, really returned to it after so many, many years away from xmpp. I tried prosody, but then after a multi-server cleanup killed it off. I think it was fine. Up next, i'd like to try either self-hosting my own ejabberd server, or if i don't want manage yet another host might consider the paid option of Snikket...or maybe go through jmp.chat which if i recall correctly includes xmpp hosting with some jmp chat paid plan, etc.
