It depends on my character. If it's a Mage, I usually go with Master Robes of X school, plus gloves, boots and head gear with no AR. I've use Miraak's attire on my last Mage and it was BOSS.
If I'm playing a Rogue, I will go with something like TG Guildmaster Armor, or Nightingale, or DB Ancient Armour... I'm not a big fan of mixing pieces, so I stick with full sets.
I like heavy armor and 2 handed weapons. Dragonbone armor looks pretty sweet, but I like orcish as well. I wear them without helmets though....a lot of the helmets look silly in my opinion(that isn't limited to heavy armor either)
