Which faction do you like the most in Heroes of Might and Magic IV?

I played the "Wrath of the Gods" scenario for the first time on the "Life" difficulty setting and completely failed as a beginner. The last time I played it, I chose "Champion" difficulty and managed to win. Although I used to play mostly as Chaos, years of experience have taught me that all factions or castles are good, and it also depends on who you're playing against.
