I've always found them the most scary. If someone has mastered one, able to control and time the weight, opening up opportunities for blows, you're fucked. A light blow with a blade or spear, you're taking shallow damage and can scamper back. But with a mace? You're off-balance now or quite stunned and that's exactly what leads to the skull being crushed in a second later.

So, sure they're slower and harder to land, but patiently, just one good hit and it's game very quickly and violently over. Not to mention, the wielder doesn't have to worry about their weapon being stuck in the dead guy.
