I depends on what you find most important on having a good sword :
Damage value as high as possible ?
Special damage bonus ? (like spiritual damage or lightning dam etc)
Extra Charmslots to give your sword the boosts you want via Charms ?
Extra Speed ?

Have you check the Dwarven smith in the Dwarven Halls ?

Good luck ! wink
