Level One comparison for ease of math.
Level 1, Human: Two-Weapon Fighting, Weapon Finesse
So the bonuses to attack are the same at base and raging, 18 and 14 Str. Daggers for the TWF so both have 2d4 damage.
TWF, Normal: Two attacks at +3 for 2d4+3 total
ECB, Normal: One attack at +5, for 2d4+3
An Unchained Barbarian that uses Two-Weapon Fighting can pull ahead if they get magical weapons, but they are still behind in the accuracy department so I think it even out a little. Double Slice will alleviate the damage drop off a little, putting the TWF ahead a small margin though.
With that in mind, I think Unchained Barbarian TWF can be less frustrating, but I wouldn't call it the most damaging.
Now where are those black opals...?

Yup, and it works just fine, though the swift action for accurate stance is slightly inconvenient. It is feat intensive, like every twf build and you don't just get to pick one stat and max it. The tools for a critfishing dual wield barb are strong.
I am glad I hit preivew. I hadn't thought about rage powers.
Accurate stance applies to both, so that is a wash. Powerful Stance is better for the ECB UBarb simply because of the accuracy it has over a TWF build.
Hmm... A Sword and Board TWF Ubarb bears some looking into, but it is much more feat intensive too...
It was a wonderful sale.
