Personally, I go for Swords. Mace's do much more damage than swords, but that is countered by the speed of the sword swing when compared to the speed of the mace swing. When swinging a mace, it feels simply too slow for my personal tastes (though I do like the results when damage is figured
).
But for my money, even my straight out Warrior-tank goes with Swords.

Swords swing faster, but Maces not only hit harder, they stagger your opponent more often, making up for the lack of speed in my opinion, especially when fighting an opponent who uses a shield. Also, in some of the previous TES games, skeletal monsters took half damage from bladed weps, while blunt weps did full damage. Skeletons in Skyrim are weak as hell though.
If a patch/mod comes out that ups the amount of Armor that Creatures/NPCs have, then Mace is definately a clear winner then.
