I've had that response several times, but XMPP is not a messaging app. It's like asking for an email client and being told "Use the internet", or "Use TCP".
Don't get me wrong, I appreciate the response, but it's not answering the question I'm asking.
What app running on top of XMPP would you suggest?
Quicksy is a decent jump from WhatsApp to XMPP for Android users (based on Conversations, but with contact discovery). For iOS there's Siskin or Monal.
XMPP has a wide and diverse ecosystem. I am working on curating a suite of XMPP software (a server you can self-host, and an app for each major platform) to produce a single tightly integrated "XMPP package": https://snikket.org/ (and https://snikket.org/about/goals/ for an idea of current progress).
