Moving to WhatsApp takes out the Apple restriction, which is a step up as I can use WhatsApp on Windows and Linux too.
The drawback is the phone number requirement, but this is true of all the other chat apps. If there was one that was functionality equivalent but accounts didn't require a number then I would switch.
