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

Many people say that Hydras are good, that as long as they hold the line, a highly upgraded hero can take down everyone with Chaos magic, but the poll doesn't mention Hydras with an upgraded hero; it only includes Hydra and its version with six additional heads, and that's it. So, in various tactical formations, I don't rule out that Hydras are good, but we mostly like to attack, and here the clear leaders are Liches and Unicorns!!! Although, I can't help but criticize Unicorns; I've only seen their blinding ability once)))))), and the Liches' archers have always caused me problems, and eliminating them has become my top priority!!!
