Having the benefits of a p2p messenger(like briar), without the problems of p2p messenger(like group syncronization problems). Cons: You will only be able to talk with other people that has a similar setup inside tor/i2p. (Good reason to share this tutorial to more people :D) Not all XMPP clients will work with this setup, but if this setup gets more popular, hopefully this will change.
