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

I thought for a long time about which creature to choose: Ents, Paladins, or Rakshasa. In the end, I decided on Rakshasa. The ability is great, plus the attack without retaliation. Paladins are also quite formidable, especially if the hero is Axel. In this case, the attack without retaliation might not even be necessary, as the attacked unit will either not retaliate at all or do so very weakly. Overall, the entire 6th level is good and very useful in battle.
