They're perfectly fine for people who haven't created galaxy destroying weapons.
My gear isn't even that hi-grade (compared to others who use full exploits), I just wish you could get more out of the Daedric artifacts. The niche items are good at what they do, but the Ebony Blade, Mace of Molag Bal, Dawnbreaker, they just don't scale well as weapons. If you could improve them reasonably then i'd have no gripe, they don't need to be on par with what can be created (value for value) but they should scale somewhat.
Then again, as easy as the Daedric quests are, I guess I shouldn't complain.
