At the time we looked for really secure messaging and voice calls, Signal did show very poor voice quality even over wifi in our country. While the choice of secure communication should be based on mentioned features, it must also be usable at least (and have decent interface for regular chats/groups). So it depends. Telegram implemented voice calls pretty good, i.e. one can speak and be heard on daily basis. I don't know if things got better with Signal, would be nice to hear the feedback from various regular users.

Correct me if i'm wrong, but there was also no incidents of secret chat leaking from the beginning, so trusting one push-provider over the other by just EFF preferences seems like a nonsense to me.
