With some friends and family members, I use Signal when iMessage is not available (those who don't use iPhones).
Telegram seems to be very tap-proof, in Germany at least the official press tried to give Telegram a bad reputation because it was used by the bad guys, like IS, right-wing radicals, vaccination opponents during Covid-19, Russians, terrorists etc.. But in the Ukraine war you can see that it seems to be very reliable for Ukrainians as well.
Maybe the attempt to give Telegram a bad image comes from the fact that the intelligence can monitor it worse than other services?
