Which monster do you like the most in Heroes 5 (level 4)?

No, I don't have any favorite creatures at level 4 when evaluating them based on combat effectiveness. And I wasn't trying to prove that vampires are stronger than lizards. It's impossible to compare them because their combat styles are very different. If lizards deal targeted, but extremely powerful damage, then vampires, due to their lower attack potential but greater ability to stay on the battlefield for a long time, gradually weaken the enemy's troops and don't always focus on the same target. That's my subjective view. And which of them is more useful? It's quite debatable. However, for a hero of the same faction, the choice is obvious. A creature like a vampire wouldn't quite fit in the ranks of the Academy. Similarly, with the Necropolis, they specialize in defense and weakening the enemy, rather than dealing massive damage.
