The mace has the 2nd highest base damage of one-handed weapons in the base game, with the Mace of Molag Bal being the strongest in the base game and the Dragonbone mace having the highest base damage with the addition of The Elder Scrolls V: Dawnguard. Despite being more expensive to forge and having a greater weight, the Daedric mace has the same base damage as the ebony mace.
A Daedric Mace requires a Smithing level of 90 and the Daedric Smithing perk to create. It can be upgraded with an ebony ingot at a grindstone and also benefits from the Daedric Smithing perk, which doubles the improvement. [Source: wikia]
