With Telegram I do not have to worry about losing my "primary" device in order to access my account. Telegram is more a social network than a chat app. Moreover Telegram does not require me to feed it my whole Contact List in order to communicate. WhatsApp has this limitation on purpose (there actually are workarounds but they are "hacks" and not how Meta wants you to use the app). It is very suspicious: why can't I search for a WhatsApp contact by manually typing in a number into WhatsApp? Instead I need to put it inside my Contact App and grant WhatsApp full access to it. LOL
