My second fav is the ebony armor, I mean, black-ish and gold=cool without the evil look of daedric.
Third is the orcish armor: looks cool and have decent quality.
Daedric is only fourth on my list: Great quality, looks cool, but I usually play a goodie-two shoes. No evil looking armor for me.
I also really like leather armor, without the helmet and shield of course: really gives a ranger-type of feel if combined with some types of clothing, but since i mostly play heavy armored characters no leather for me when I'm no RP-ing.
What about you?
