What to use for real-time chat application

Question

Im developing a chat application just like omegle.com with some more features for my college project. I want to know which would be the best approach from following two and why:-

1. NodeJS + Socket.io
2. Rails + Faye

I searched a lot on these two and somewhere it says about 1st option and some 2nd. (mostly 2nd)

Please help me here because im little confused which to use as im searching and reading on internet from past one week and didnt come up to any conclusion and already wasted my lot of time.

Any suggestions might do as it would help me to kickstart my project.
(Note:- If there is any other approach then please suggest it.)
Thanks :)
