Do you like realistic nord (viking) armors(Iron,studded,scaled,steel plate,fur,stormcloak)
I Prefer Banded iron armor!
For heavy, its Orcish. It looks tough but it's not over the top. Also, as long as you continue to advance your smithing skill it's the last set of armor you'll need to make. Right now with my smithing at 80 something and with some solid Fortify Smithing potions and gear, my characters armor rating is is 600+ with Orcish. I don't need to worry about chasing down ebony ingots for the next set of armor---or Deadric or Dragonplate.
For light, it's Scaled. Looks good on female characters and I've gotten the armor rating as high as 550+ with it.
