I've mentioned this before but SimpleX is more private secure and anonymous that signal threema and session.

SimpleX is decentralised meaning taking down a single group of servers or org wouldnt destroy the simplex network, people can run completely anonymous simplex servers over tor, this puts simplex ahead of Signal and Threema

SimpleX has quantum resistant encryption which puts it ahead of Threema and Session, the UK military[1] and NATO[2] both consider quantum computers to be a threat now because of store now decrypt later attacks

SimpleX has no user identifiers not even random strings, its essentially like having a "burner phone for every contact". Two or more compromised contacts could corroborate your messages by linking them to your signal username or your session id, but with simplex your contacts can't prove your identity even between eachother. This fact puts SimpleX above Signal Threema and Session

These technical details about the simplex protocol can all be found on the project website including the whitepaper
