- no ecosystem fragmentation
The Matrix spec includes e2e encryption, multi-device, etc, so there's no need to make sure specific XEP's are supported or whatever

- much better clients
Element isn't perfect. but it's soooo much nicer to use than all the xmpp clients/apps I tried in the past

- actually federated rooms
instead of 1 spof server having to act as a router, matrix federation is a full mesh between servers that participate in a room

In general this kind of stems from quite a different design philosophy, XMPP is bare-minimum message-passing (although it can be extended), Matrix builds chat on top of a federated, distributed data store, which makes things a lot more reliable both for federation and (historic) message availability

lastly a headsup to any non-mutuals about to jump in i'll probably ignore you.
