It seems that no matter how i play every character of mine ends up with dragon bone,dragon scale armor this makes each character feel less unique, I think that there should be more then on type of strongest armor, each designed with different perks like, protects more from evil/ good or other assorted benefits this way every single player of skyrim wont all end up looking exactly the same and each character is more personal. (The same could be said about weapons also.)

Are you satisfied with the way armor is set up in skyrim or should there be a bigger variation?

Well, you shouldn't go for best possible armor, just goes for what looks nice.

But I think there should be a dressing room option for every piece of armor so you can toggle stuff on and off, like pauldrons, chestpiece, right or left glove.

Jeweled.
Ivory.
Trollbone.
Animal Hide, Sabre Cat, Wolf, Bear, Troll, Vale Deer, Snow versions of animals etc
Aetherium
Chainmail.
Mithril.

I want some more realism in Skyrim, some Chainmail, some stuff like the guards wear but legally obtainable, etc.

I usually get some decent guard armor from dragon corpses after defeating them
