If you want to argue that Telegram and Signal are comparable because Telegram has better UX and Signal better security and some people prefer UX to security, that's fine (I could not disagree more strongly, but at least it's a coherent argument). But don't pretend the thread isn't about security to make people believe that there's controversy about whether Signal is more secure. There is no controversy: Signal won the Levchin prize this year for the Signal Protocol and sets the standard for secure chat, and Telegram... well, let's just suffice it to say that it does not meet that standard.
