Signal have E2EE. Facebook decided to copy the idea to Whatsapp. AFAIK, attackers have always gained access only by other methods.
Telegram created their own protocol, MTProto. E2E is only enabled on private chats. By default private chat exist only on the device they were created on. So a lot of people don’t really use them.
So, in terms of encryption alone, Signal/Whatapp are safer.
I don’t know about you, but for me, the last company I’ll trust with my information is Facebook.
So if you can, use Signal.
If not, decide who you trust more. Telegram or Facebook.
Just to clarify. I thought WA had e2e encryption before Signal but got bought out by Facebook, so Signal developed including with e2e encryption and open source code (at least initially) as an alternative. Is that correct?
The Signal protocol (née TextSecure protocol) was created by Moxie Marlinspike and Trevor Perrin and Signal messenger (née TextSecure) was built from the ground up with e2ee. WhatsApp was acquired by Facebook without e2ee and Moxie later worked with them to integrate the Signal protocol for WhatsApp. Hope that clarifies.

Signal considered the best between those 3 apps.
