IMO - ASUS is the only true 1337 high-end motherboard manufacturer - hell, they even go the extra distance to include pointless bells and whistles just so they can charge $100 more than their competition . . . and people still buy them like hot cakes! Even if I wasn't ASUS loyal, that right there would say something to me, if people are willing to pay that much extra for a high-end board.
One day, I swear I'm going to prove my "an ASUS motherboard is truly bulletproof" theory, and post the vid online . . . I just don't currently own a gun, and am too lazy to get the permits and all . . .
Anyhow, I used an ECS years ago, and wasn't much impressed . . . it wasn't too shoddy, TBH, but it had problems that mimicked other failing components every now and then. Perhaps it was just bad circuitry/PCB architecture, not sure . . . but it was thrown in the trash and replaced with an Abit.
