i still dont get why people care about how their items look. all i care about is stats.
Looks are so much more important. As far as the game will allow, of course.

(I really loved the Reinforced Leather Armor in FO:NV. Great, great look. Tried to keep it as long as possible, but the Damage Threshold system meant that I eventually was forced to upgrade. Such a shame. On the other hand, it's nice that the Fallout games were never hard enough that I had to use the Power Armor.... that stuff is ugly as sin. Will never touch it.)
edit: I think my favorite default Skyrim armors (female) are Leather and Steel (no shoulderpads).
I'm with K2 on this. Looks are very important. I play 3rd P, so I like to see my characters. People that mainly use 1st or people that just care about the action side of the game. Tend to not care about looks or character creation either. I can easily spend an hr in the creator, just to get my character the way I want them.
As far as which....It depends on the character. Some will look better in one type over the other. Just because it may be more fitting for that character. I tend to favor the heavy armors over the light. Ebony and Daedric are right up top.
