I would say you go with MoongooseIM. Its a much optimized fork of ejabberd with some things done in a much nicer way ... It support redis session backend , encrypted password, xmmp over websockets to name a few. Disclaimer:- I personally work on chat server and personally prefer moongooseim to be one of the best available right now.
