@David天宇Wong it is, but it is better than Telegram's.
I think the best to answer this would be to ask a formal question on our main site (Title: "Why is Signal better than Telegram?" / "Signal vs Telegram: which protocol is better and why?")
informally (may forget some aspects) I can think of the following points:
a) Signal is made by cryptographers (Marlinspike et al), Telegram's protocol is made by mathematicans w/o cryptographers
 
signal is closed source, telegram is open source
(I'll play the devil advocate)
 
(frederic jacob at signal as well)
ah :| where did I hear that signal was closed source
 
@David天宇Wong the predecessing company to current OpenWhisperSystems has been bought by Twitter and they may have made something closed source...
b) Telegram's protocol is completely rolled on their own, Axolotl (Signal's protocol) is based on the well-received OTR
c) (late point) Telegram's protocol has been broken, Signal's not
d) Axolotl uses well-analyzed primitives in well-analyzed ways, Telegram doesn't (see how the authenticate data and that they use IGE)
 
well I haven't read much about both
can't add much :D

Those are the points I know spontaneously, after some research some others may arise...
