WhatsApp data leak: 500M user records for sale
Signal uses SGX for remote attestation, which presumably lets the client verify that the code running on the server is a build of the OSS code and not a modified version. But I don't know the details or if this is reliable.
SGX and remote attestation described here:

Types of Execution Environments, Attestation and SGX
TEEs have numerous privacy-enhancing applications that may benefit users. One of them is, as discussed earlier, private contact discovery; the Signal application uses a contact discovery service enhanced using Intel SGX, a TEE technology, to protect its users' privacy. A similar application of TEEs is performing malware analysis in a remote cloud service, so that the service may not identify users by the contents of their devices, such as the applications they have installed, especially important as 98.93% of users may be uniquely identified by the list of applications they have installed.

Twilio Incident: What Signal Users Need to Know
Signal (or, more accurately, one of its predecessors) used to use client-side private set intersection for contact discovery, but this scales poorly [1].
Now they use a solution based on Intel SGX and server-side trusted computing [2].

Have you tried any decentralized messengers?
Try Jami https://jami.net/! I'm kind of blown away by how well it works! I originally tried it about a year ago, but it was kind of a pain. My issues with it were fixed when they incorporated UnifiedPush. However, since iPhone will never have something like UnifiedPush, I wouldn't recommend it for iPhone users or people with many iPhone-using friends to convert.
