They're all very similar and you probably won't go wrong with any of them.
For me, i'd go with the Gigabyte Aorus board over the other two.
I prefer ASRock > ASUS = Gigybyte.
So i would of thrown The Taichi as a competitor.
Are you a human?

I am using ASRock right now but ASRock are mostly OOS at the moment !!!
oos = out of stock.
But that newegg link i gave you has it in stock.
And if you look at the board it has its own vrm fan, as well as a chipset fan.
