I very much dislike WhatsApp. Especially compared to Telegram. It's has not been innovative in any way since 2014. All of their new features are basically copy-cat from other services, and even when implemented, they don't work very good. The desktop client is an extremely slow Electron app. And the worst thing is that I have to backup WhatsApp manually to my own cloud service which is pretty stupid.
I operate hundreds of WhatsApp groups to facilitate virtual business networking and my clients love it. As do I.
free, easy to use, popular, worldwide, video calling, status, connect your contacts....the best
