Which creatures from the alternative upgrade options do you choose?

For the Order faction, I chose:
Level 1, I almost agree with SEVER here; the upgrade hardly makes a difference. Peasants still give 1 gold each day, and if you're playing as Elaine, it's even 2 gold. Well, if you still want to upgrade, I think the alternate upgrade – Landlord – is better.
Level 2, I haven't decided yet, but I think the alternate upgrade is better.
Level 3, I think both the Lancer and the Fanatic have a 50% chance each. One has great defense, and the other has attack.
Level 4, I also think the red Griffins are better than the Royal Griffins.
Level 5, Inquisitors seem better than Adepts, but it's up to each player.
Level 6, I prefer the Paladin (Knights of Isabel, Paladin in English, it was just translated incorrectly).
Level 7, I like the Archangel with resurrection more.

For the Orcs, I chose:
Level 1, the Goblin Shaman is better.
Level 2, I prefer the alternate Centaur Marauder.
Level 3, the Orcs with the large shield are more powerful.
Level 4, the un-upgraded Shamans are super! But the upgraded ones are stronger, so you have to upgrade them. I upgrade to the Daughters of Earth.
Level 5, I chose the Orc in a helmet and armor; he is stronger.
Level 6, Paoka are not my thing. I prefer the Dark Wyvern.
Level 7, the Blood Cyclops are better. They shoot with their eye, which is cool, and they are strong.

It's great that they added alternate upgrades. Now there is more variety for each creature in the game. Before, there were only two types: upgraded and un-upgraded. :)
