Mirdan Hammer's are a fiendish weapon, but mostly for PvP, due to the it's overall AoE combo when it's held in 2H. Normally people go with Crushing or Moon Mirdan Hammer's, they are pretty fearsome.
For PvE, they're not actually very good.
For Blessed Builds, the Mace is one of the best weapons, especially due to the magic damage and the extra damage for armoured enemies. Knight's sword physical attack may be higher, but when you're doing magical weapons (Blessed, Moon, Crescent), you tend to disregard physical damage for magical damage.
You could also look for Morning Stars, they're the equivalent of Blunt Uchigatanas because of their Bleeding effect, but overall, Blessed Mace is the better choice for 1H
