Both Synapse and Riot have been working well for me. I’ve been running my own homeserver for a while now. I use it daily to communicate with a few of my friends. We all use Riot. They use it on Android, I use it on iOS. Riot is well polished - polished enough that I was able to get my non-techie friends to start using it without any issue.
