Honestly I would perfer signal. Telegram should have better owners, but they are no way super trustworthy. At least signal is actually end to end encrypted, in their released source code, while telegram claims security while being as encrypted as like whatsapp which is in no way free from snooping. Though session is the way to go if you really want security and a trustworthy owner.
Ironically, Twitter owns Signal... or am I mistaken
I'm hearing Telegram is the way to go.
I made a post actually asking "How secure is Signal, really?"
The replies were...discouraging...
