Asrock has come a long way lately. They are a good board manufacturer. But if both boards have everything you want and the only difference is appearance, I'd probably pick the Asus. Asus is a tad higher in quality than Asrock. In fact, Asrock used to be a subsidiary of Asus; they made their OEM boards for Asus. And Asrocks always had an issue with board thickness. They are quite thin.
