I haven't used Signal, so I don't know much about it. I know that Telegram has native clients for multiple platforms (real apps, not HTML/JS apps). For example, its Windows client is written in Qt and works on Windows XP. It is also very realiable and works good even on bad mobile connections.

Telegram has channels - it is like a microblog where the owner can post messages and images, and everybody else can only read them.

And in Russia Telegram is well known (unlike Signal) because its founder (Durov) is also a founder of social network VK.

Judging by screenshots, Telegram and Signal UI look similar (well, almost every IM app looks the same).

As I understand Signal, as Telegram, requires a phone number for registration and therefore doesn't provide much privacy (the government can easily track your location and identify you). I wouldn't give a real phone number to any of them.
