I've used most motherboard brands and I've seen them both be very reliable or randomly bad, but I'd say they are one of the best brands out there as long as you don't go for the cheapest models. I still own 3 gigabyte motherboards that are 8, 6 and 4 years old and work just fine. But I've had to replace some for my customers that weren't that old. But they don't fail more than other brands like biostar, asrock, ECS or intel.
