What are the main not-working-smoothly problems you're seeing with Vector Web/Android out of interest? Matrix Console is very much a raw dev-focused app on top of the SDKs, but at this point in its life Vector should be relatively polished...

ejabberd obviously is much more mature than synapse, but i'd be interested to know where synapse had problems getting off the ground - it's been a few years since I've run ejabberd, but it wasn't particularly fun at the time, and I'd hope that synapse can do better! :)
