Apart from the Skeleton Key, which I only got as a cheat, I admit...None of my characters ever had anything to do with Daedric artifacts...
My fave "Thing" in the game is the Escutcheon of Chorrol...Which, depending on the level where you did the quest for it, had a different (higher) damage reflect percentage...

...That, and it's absolutely gorgeous too...

Chillrend is a close second though...Another gorgeous thing...But, like Grits, not one to use long-term, but looks lovely on a sideboard...
