IMHO, Signal main advantage is that you can sell it to your parents and friends like "WhatsApp, but safe".

It tries to have feature-parity to WhatsApp; looks the same, works the same. All this while researching innovations on cryptography that doesn't compromise user experience too much.

In my experience, doing exactly what WhatsApp does (but safer) makes it an easy sell to people around me.

True, though Signal annoyingly wants the user to also enable it as SMS app. From my own experience with relatives this can lead to a lot of confusion among non-technical users, for example when they try to send a picture to a contact and it fails because that contact does not use Signal. From what I've seen Signal does not clearly show a difference between those two groups.

Other than that it's definitely a great alternative.
