Unfortunately the usability of the available Matrix clients leaves a lot to be desired. When we evaluated Element I think it was in a particularly buggy state.
In contrast, Zulip is fast, simple, and “just works”.
Spring 2022, when spaces were coming out of beta. My boss tried to switch spaces and got a completely blank white screen. Not a good look.
Personally I use Element every day to keep in touch with the Matrix community, and it works fine for my minimal needs. It’s better now than it was then.
