Of the ones I’ve tried that are fully open-source is the best ons regarding UX functionality.
For example, Matrix is a UX nightmare, with many different clients implementing different features, or having issues if a non-default login mode is used, ending in people getting locked out after the browser logged them out because they forgot to copy a key when they were logged in.
Others like rocketchat are opencore like matter most, which means they can do the switcheroo.
The things I would care the most when checking this kind of service are:
UX: how easy it is to use for nontechnical users
how well-backed is the project, socially and financially, to ensure it lasts a long time
how easy it is to get the (public) conversations out, as an exit strategy, if the one above isn’t looking so good.
