What are the most serious secure messengers?

I personally like the approach Threema has. They provide their own push serice called Threema Push[1] which is opt-in for google play store version. The push notifications for Threema do not contain any sensitve information either way.[2] They also have a libre version on F-Droid.

Their web client is based on angular.js - i wouldn't dare trust it with private information.

Threema may very well be the Crypto AG of our times
