Jw-dom: The only place you will find that the "Prince of princes" (Jehovah) outranks the "King of kings" (Jesus).
It would be a fun exercise to use the same logic used to "prove" that Jehovah is "Prince of princes" on the text in Revelation where Jesus is explicitly referrred to as "King of kings", and then see how the JW would try to squirm out of that one.
At times some people ask "If a JW comes to my door, what do I ask him?" I think the above would be quite fun.
