Signal is easy to on board folks to. Not a huge fan of the phone number requirement, but it’s worth the trade off for me. I used Session for a while, but media sharing was buggy. I’ve heard good things about Simplex, but the inability to have a desktop client was deal breaker for me.

Anti-Brave?

Even with e2ee, I wouldn’t trust it since they use a closed-source, proprietary encryption protocol.
