When I decided to try XMPP, I had to do a lot of research to decide which applications I should use for the server and client. I did not experience this in Matrix. And yes, I know Matrix is ​​not stable. I am not against that. It’s just easier to get on board.

If we told two people to use these two software independently, they would start using Matrix much more faster than XMPP. I think this is enough to call it uncomplicated.

Also, would you recommend Snikket server (or Prosody) for 1:1, group calls and screen sharing?

I don’t want to defend Matrix. I agree that it is not stable and lightweight. However, I believe it is simpler than XMPP. Wanna set up a server? Synapse. Need a client? Element. The default softwares are easy for new users to discover.

Also, the fact that Matrix has a single protocol means that in theory all servers and clients can work with each other (Although I know we are far from that at the moment). It is much better than XMPP’s XEPs in terms of simplicity.

It’s not that I don’t like XMPP. I want a stable, encrypted, federated messaging platform. However, in terms of money and motivation, Matrix seems to be closer to that right now.

way less complex

I don’t agree with this.

Huge!

Ensuring that Unable To Decrypt (UTD) bugs never happen. Huge amounts of work has gone into this over the course of the year, especially via complement-crypto as a comprehensive end-to-end-test suite for both matrix-rust-sdk and matrix-js-sdk based Matrix clients. We are finally at the point where UTDs are so rare that most people simply never see them.
