Unless you have spellcast, Aurum Sabaton win.
Why?
Because the Unicorn have a fairly specific latent that is a bit of a pain (as a good WAR will be taking a few hits), and they are next to useless if the latent isn't active.
They also lack the accuracy of Aurum, so Unicorn would only win if the latent is active AND you are at ~93% hit rate.
If you have spellcast (and are able to write advanced rules) you could use Unicorn while the latent is active (only against targets that you will be near capped hit rate) and switch to Aurum for the rest of the time.
