We've been using Zulip for ~5 years, I won't describe it as awesome.

E.g. it takes a minute to open a chat on mobile, but only few seconds on the web. No idea how it's possible if they use same underlying DB.

In fact a full text search over years worth of communication is faster than loading latest DM from a specific person in a mobile app!

And not much improvement over years: few things became nicer. But mobile app was always dogshit.
