Depends on the use for which the board is chosen. For high end gaming, the choices narrow quickly... but the video graphics card, powe supply, and memory are equally important.
I am not an ASUS Fan because we have been unlucky and have had large numbers of early failures of ASUS, but am very happy with MSI, EVGA, ECS Elitegroup, BIOSTAR, FoxConn, DFI, ABIT, Sapphire, SuperMicro and Tyan.
FoxConn is a favorite because of their reliability.
You might enjoy the monthly motherboard reviews at TomsHardware.com or AnAndTech.com... very, very detailed.
The problem with motherboards is there are too many new releases every month, and it takes weeks or months for the bad problems to be corrected, or for new problems to appear under use.
For gamer boards, your choices are much more limited... ASUS, Biostar, EVGA, and MSI are better...
No company consistently makes good boards. Pressing a good board takes several revisions. So a smart builder waits until a motherboard has been out for six months or more... particularly ASUS.
