Anybody here using XMPP or Matrix regularly? I'm in a few group chats on both, and run my own personal server for each. Both interesting projects with a similar goal. What are your thoughts?

Matrix is laggy shit, much worse than discord, though also less censored. XMPP (aka jabber) chats were decent, though they were barely different from irc, and they didn't support media thumbnails. They had less issues with different codepages than irc, it was a bit easier to use.

i would use matrix more if element/riot wasn't so slow.

If you don't like element you can try and different client like nheko

matrix is garbage, xmpp is not very populated

I use Matrix regularly and even administer one of the groups. But Matrix is garbage, literally the worst "private" messenger technology.

Matrix: slow, ineffecient, buggy, and made me hit out of memory problems on a phone with 2GB of RAM.
XMPP: faster, effecient, and ton of garbage clients. Sure they work, but unless someone creates a Discord-esque client for XMPP I don't think it'll gain popularity other than being used by a group here and there for a month or so.

I never had issues with Matrix using Element. I wish the alternative clients were better though, some of them have good design but lack crucial features or buggy.

I've been using Martinix for a while, and now only run a small group and haven't tried a client other than element, but the experience isn't great, and Gitter's sidecar isn't that good anymore.

XMPP is commonly used, but I'm not used to it.
