I really like Wire, for a large number of reasons - privacy and user experience among them. I've talked about it in the past[1].

If you get the time, please give it a proper whirl. With the recent open-sourcing of their server and proper E2EE by default[2] (but abstracted away from the "regular user"), it's shaping up to be a really solid application. As far as I'm aware they use the same double-ratchet protocol as Signal, but you don't need your cellphone number to register (a big thing for some people - myself included).
