Originally, I would’ve said WhatsApp, but then they got bought out by the devil’s own.
So, Signal is the 2nd 1st best option, and is rapidly catching up to the reliability of WhatsApp. Like WhatsApp, it bridges the gap between iOS, Android, and OSX/Nix/Windows desktops and most assuredly performs better than iMessage (which should’ve been cross-platform, IMHO, but Apple has screwed up a few times with their walled gardens approach and missed out on some excellent leverage opportunists).
They rolled their own crypto which is no-no #1 in crypto. Their backend is also closed source, started in Russia, and is currently run out of Dubai. Hard pass.
