My experience with Matrix is that the federation itself is a deal breaker. I have a pretty beefy server and good connection which was getting ddosed by running Matrix and timing out on so many requests for avatars/profiles etc. Maybe I did something wrong, but the whole experience rendered me quite skeptical to the viability of it as a federated chat.
That said I've had nothing but good experiences using it with big servers set up by pros.
