I know that Glass is the best light armor and Daedric is the best heavy armor but what's the best medium armor, Orcish?

I think so yes, but I don't worry about what's best too much, just think about what suits my character best.

Some enchanted items that are medium armor is better than the orcish set. For overall set wise I would Orcish is the best

This is kind of in the same area so I wont open a new thread but can someone tell me what the best robe for a wizard is.

for unpatched version, the best was the robe that can give +15 to hp and stamina constantly. forgot it's name though.

the patched version it was change to give +15 hp and stamina per cast. still a good robe though.

The Robe of St. Roris?

sounds like it.

What about dreugh armor? IIRC it's better than orcish, both in weight and armor rating... difficult to find though.

Well its got better armor rating but theres onlt the helm, cuirass and shield. I was looking for full sets.

You are right... 18 cuirasses, 12 helms, 9 shields, 0 enchanted cuirasses, but no other armor pieces... too bad, they are really good
