I don’t know man, seems to me XMPP is more secure (unless you trust Signal) and simple to use because you have to jump less hoops

If yo run your signal server does it come with the new quantum E2EE?

And how do I tell may client to use only a specific server?

I’m using molly for several months now it is really nice but recently I dive myself in XMPP and it is superior to molly/signal just because XMPP servers are auditable amd you can actually see if the server is using encryption or not while signal servers are closed source unfortunately, it’s their only flaw
