XMPP server : ejabberd vs openfire vs prosody

Question

I'm trying to figure out how XMPP works (total beginner in protocols in general) and I want to set up a server.

So far, I saw 3 main challengers :

• ejabberd
• openfire
• prosody

I checked on some website and on the wikipedia, but I cannot see pros and cons about all of them.

Where could I find some understandable informations ?

PS : if context is somehow important, I want to set my server on my personnal raspberry pi (so not that much processing power), and my ultimate goal is to use XMPP for a little android app using google cloud messaging
