If you take barb its more for rage than for unarmored defense.
Extra damage and hit chance plus getting half physical damage is fantastic.
A medium armor will give you a higher AC than unarmored defense, and that does not even take into account that the armor may have other useful bonusses.
If you take the classes as decribed in the initial post you will not get a feat/ASI or a second attack for a long time.
