I respect Signal. My primary rationale is that I do not routinely meet people who use it. Coupled with the reports of subpar UI, so far I have chosen not to go through the friction of setting it up and converting my conversation partners to it. Between Telegram (product co-developed by the creator of the Russian clone of Facebook, owning company of unknown organizational structure) and WhatsApp (product co-developed by co-founder and current CEO of Signal Foundation, current owning company spent a lot of time in recent years under high scrutiny), I consider the latter more trustworthy despite some of its drawbacks.
