What are the differences between these motherboards?

Solution
I had a GA-Z97-HD3 for a couple years before I decided to update the bios and it led to me having to RMA it, and I recently got the Asus Z97-A/USB 3.1 while my other board is getting rma (imma use that for another pc) but yea they are both great companies. Gigabyte i tend to refer people too just because the one I had never had any issues. Customer service with all those services is kinda eh. EVGA has the best customer service imo.
