I like Asrock. they have come a long way since they first started. Then they got bought up by Asus, learned a lot, Asus turned them in a wholly owned subsidiary and they make good boards at good prices that rival boards that cost almost twice as much.
Gigabyte, I don't like and have had more or seen more failures of them than other boards, so I stay away from them.
Asus is a brand name that charges more for that honor of owning a Asus, but I find Asrock's rival them for less.
That's based off my observations anyways of building and repairing PC's and running my own business doing that.
