I didn't vote because none have given me any problems. I've only used two, Abit KN8 and ECS NFORCE4-A939, and both have worked just fine even overclocked (yes the ECS has full overclocking abilities including voltage). I personally like the Abit better overall because of the BIOS CPU fan control plus the location of the chipset and the "standard" push pin chipset HSF attachment versus the ECS using loops (like Intel 865/875 boards). I do like the layout of the ATX power and 12v connectors, plus the USB headers on the ECS board. The Abit board is close, but not as nice and near the edge of the PCB as the ECS.
