No, I know. That is why I don't say this lightly.
The only really safe form of communication is to meet in person at a remote space (no wires;),) as an infosec contact pointed out some months ago.
It is always a trade off.
However, with the FBI getting relatively easy access (see my TL) to any US based server and with the increasing overreach of local law enforcement, the server location is as important as the organization behind it.
This pretty much eliminates most...

...US based services. Of course, China and Russia are even worse (see my TL.)
That said, I'd like to reach a consensus, which of the apps, and there is an interesting French librarian post here that has more alternatives, is the best option for most that are willing to invest the 5 bucks (if necessary)and a bit of time, but are no techies and want to include their non-tech savvy family and friends.
I guess hardly anybody will have a smartphone that is not connected to..
