I like the look of Ebony. Classics niether good or evil just Ritzy.
I also like Dragon Scale armor but since I Wear heavy armor that isn't an option.
Dragon Plate is so Primative in style. Althought the Hvy Dragon Shield is nice.
Deadric is deffinately a statement saying 'look at me I'm a Deadra Wanbe kill me first.'

NPC's responces to armopr types:

Followers of Stendar should at the very least run up to you to check if your a deadra or just a fool.
[PS: They don't seem to care that you summon deadra in thier presence even though they say they Hunt Summoners.]

I had one heavy armor guy join the Blades and their armor is pretty cool and nice AR. Also had a Nord who used the Companion armor which looks nice, but terrible AR, needs lots of upgrading.

I have actually never worn Daedric just because it just yells out evil. I have also never worn Elven as it just screams Thalmor.

Guards will sometimes remark on the type of armor you wear. "Ah thats some fine armor. Good old fashioned shteel." ( to me it sounds like shteel, and not steel)

Its nice to see some good looking armor. A lot of the stuff in Oblivion was ugly.

IRON HELMET AND SCALED ARMOR ALL THE WAY!!!!

Shrouded cowl and nightingale are the best light armors.

The Ebony is beautiful, but the helmet is a little narrow-ish. I wear Daedric on my dude, but I realize that realistically it's too hazardous with all the spikes and points.

On my chick, I generally wear Forsworn or Fur with the bikini+shawl top, but usu the Forsworn because the Fur Helmet is too clunky looking.

Honestly, I like all the armors to a great extent. Best, in my opinion, are Penitus Oculatus, Scaled, Scaled Horn (quite sad you can't upgrade it), and Stormcloak Officer. Scaled + Skyforge Steel weapons = Awesome. But again, all of them are great.

I prefer Steel Plate for my characters who wear Heavy Armor. Dragonscale for Light Armor.
Steel Plate is also obtainable at a lower level than most of the higher end armors.
