Which monster do you like the most in Heroes 5 at level 5?

In my opinion, the best is the 3rd Unicorn; it deals good damage, has a decent amount of health, and can move far. The 2nd Lich is also good, and the Adept has good defense, but Hydras will fall after passing the middle of the battlefield; their health won't save them. In general, the Unicorn is the key.
