Which creatures from the alternative upgrade options do you choose?

The new feature is certainly great; it should be implemented for all units in the next expansion pack. -.- The phrases like "I'll hire new mages if the enemy knows Chaos magic" or "I'll hire someone if the enemy has many units" are amusing. I'm curious how you would do that? Will you ask the enemy to tell you how they're doing? What skills they learned this turn? Or will you ask them to split one unit into several so you know exactly who to hire when there are many units? In reality, whether one unit is better or worse is nonsense; I use different units depending on my mood. Although, some are quite poorly designed. For example, I don't like the new Furies. Tu Knight: Goblins reduce enemy spells by 2 times and take on the debuff (I don't know about buffs, but I think they take those too). Regarding the Knights: Isn't maneuvering almost the same as having no penalty, but better? Everyone says, "They're good in combat because if it comes to melee..." And so what? The Marauder can just run away and that's it, and they'll retaliate without a penalty. Plus, their damage is slightly higher.
