Well, technically it is as saint19 said. Personally ASUS is my favorite as well then it goes down to what the board can do and its chipset. If anything EVGA isn't the best, but they're definitely not the worst either for motherboards, basically in between.
Asus-Gigabyte-MSI-Evga... I have 1366 boards of all the four brands, and that's how i'd rank them in terms of value, ease of use, quality and overall performance... No brand loyalty or prejudice here, just facts from personal usage... Lol
