I always roleplay as Phillip II since that's the best way to warmonger as him.
I find that the roles leaders have are generic strategies dialed up a notch (different religions, city-state killer, city-state competitor, enthusiastic disciple).
Anyone can use the Wars of Religion card, conquer city-states that don't belong to them, maximize envoy usage, or leverage an outside religion; so the roles they have is a way of exploring the plethora of strategies out there.
