This doesn't mean Prosody is 'inferior', just that it targets a different profile and can be a simple moddable solution to start out with. This guide focuses on the easier setup that's possible in Prosody 0.12 and later, which a majority of guides don't cover yet. While most Linux distributions only offer 0.11, it's best to start on 0.12, to not have to later reconfigure some services from 0.11 to 0.12.
