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

Definitely better. But you have to keep in mind that there isn't a unit on level 7 in HoMM V that's worse than the Archdevil...:(

You're wrong about the Archdevil! It's very unpleasant when they summon several more dozens of Cave Lords...:smile16: And even without that, they're not weak at all...
