I prefer the old ones; the new ones are only good as kamikazes.
Fire Hounds are definitely the best, as I already wrote, they’re like a self-propelled, three-barreled flamethrower. It’s a pity they die quickly:(
Always Succubi. No comment.
It depends; I don’t feel a difference (although if warrior luck is maxed out, you can use the old ones).
Pit lords, see above; by the way, the new ones are good for taking out numerous but low-level units, like peasants.
Devils, the new ones are more durable, they look cooler, and in general, I rarely make it to them.
