On my side, I'm running a eJabberd server for the last 4 years for my family and friends.
It runs on a 2Gb RAM cloud based vm along movim as web client for blogging and chatting.
My friends and I are running Conversations or Monal depending on the smartphone they're using.
For desktop, I use Gajim or Dino on Linux.
Sometimes there are few problems with OMEMO but it's usually linked to the fact that people changed phones or use new client messages were not encrypted for.
