The primary and most important feature of a messaging app is the ability to message a lot of people.

Signal is the best messaging app, but not by metrics people use to measure messaging apps, because not a ton of people use it. I use signal, but I also still use SMS (garsp!) because ultimately sometimes I just need to send a message.

It sucks and it's stupid, what we need more than anything else, more than any app, is open and federated messaging protocols.
