I think since the P6 series have come out things have been better from Asus.
My experiences with the Asus P5 series board both intel and nForce chipsets was not inspiring, I get the impression component quality was let slide a bit. (Not uncommon for LAN ports, DRAM sockets, chipset, etc. to be DOA or degrade over time). Had to RMA quite a few nForce and 965 based boards and P35 wasn't immune.
Gigabyte aren't perfect but I'd rate them over asus on build quality. Mine have been flawless and overclocking monsters but I do know 1-2 people who have had niggles with them especially related to booting with certain USB devices attached.
