>How much more secure is that?

It's much more secure wrt metadata. There is no third party server that's able to amass metadata about the two users conversing. SimpleX doesn't hide your IP-address from the server, and given that there's exactly two parent companies hosting ALL of the official servers, it's not too hard for Akamai or https://runonflux.com/ or anyone who compromises their OOBM systems to perform end-to-end correlation between two users.

https://discuss.privacyguides.net/t/simplex-vs-cwtch-who-is-... has a lot of discussion about Simplex vs Cwtch.

Agree with your post, but do want to point out that using private message routing on SimpleX theoretically hides your IP address from the server[1].

Similarly, built-in routing over Tor can make performing correlation attacks difficult for some adversaries, and if you elect to use your own .onion servers instead of the official ones, it adds another layer of obfuscation.

		What do you mean by "own .onion servers" here specifically? It is ambiguous for me. Your own hidden service? Your own bridge? As for hidden services, that would be up to SimpleX to do so (just like how Ricochet does it), otherwise I have no idea how one would do it with SimpleX or configure SimpleX to use "mine". You would need Orbot on Android to begin with to use SimpleX with Tor, and I do not know if there is such an option to "use own hidden service", as hidden services do not work this way at all. How do you configure SimpleX on Android to use your own SMP servers BTW?
