You are kidding yourself if you think Daedric should look anything else. It was always the "ultimate evil armor" option in the elder scrolls games. It looked okay in Oblivion but it (like all the armor in that game) suffered from being too cylyndrically shaped. Morrowind's Daedric looked pretty bad-ass, and I think Skyrim's is one of the best in the series. Actually, the armor design is pretty great accross all fronts for Skyrim. The only one that really lacks IMO would be Dragonplate, which some would consider the "good" version of Daedric. Even then it still looks pretty good, but its very barbarian-like, so as such it wouldn't be too appealing to use for a paladin for example.
Though when I use armor, I don't do it purely to get the best stuff - I use whatever is good AND looks good the character I am playing. I'll for sure be using Daedric for my evil mage, though I might end up using a bad-ass set of robes instead
