WhatsApp obviously more encrypted than Telegram since later have no proper E2EE whatsorver by default and also sync all history from server.
Its still preferable to use Signal since now it actually supports numberless registration. Hopefully they will actually fee payable not via credit card at some point.

It's preferable to use Signal because they don't collect as much metadata as WhatsApp, and the client is open source.
I don't care so much about the numberless registration. Actually I don't even understand why people care so much about it.
