WhatsApp has an e2ee backup option and according to Signal WhatsApp doesn’t have a backdoor. Telegram does not encrypt group chats, which is terrible for privacy and security. Hiding the phone number is a solid feature, I admit. But it hardly protects you from the government, especially if you become a high-profile target.
That is the biggest reason I don’t trust Signal. They implemented Whatsapp’s encryption and while technically the encryption hasn’t been broken, the way it works forces you to leave data on your device, which has been proven dangerous in practice for the kind of people it sets out to protect.
The encryption is set out to protect people from man in the middle (server admins reading your data). If your device is compromised then nothing can help you, the attacker can just open the app

no matter what security you use when the attacker gets access to your (unlocked) phone you are fucked either way.
Data will always be on the end device unless you turn on disappearing messages which you can if you are concerned about that
