Which monster do you like the most in Heroes 5 (level 6)?

I'm disappointed with the Messengers. They don't have enough hit points, even though their damage, attack, and defense are quite good. But they are too expensive, and it's not profitable to upgrade them. However, I like Ents more and more. It's a joke – 180 hit points, decent defense, and they are cheap! Plus, the Elves have a building that increases their production. I guess if I weren't playing as Necropolis, I would be playing as Elves.
