Chaos is probably easier because you just need to go all-in on one vibe, but even this soulblight one is better. The new vampire lord is the centrepiece but he's surrounded by thousands of undead, he has this creepy little undead dog at his side hinting at a human connection, he looks ethereal and is staring sort of beyond the horizon giving it an inhuman feel at the same time. You can do model art and not have it suck as long as the artist is good.
