Asus has been the only brand historically that either never sent me a DOA or lasted longer than 1 year. It's always about models and not brands but MOBO's are pretty complex, sensitive pieces of equipment so I tend to stick with them so long as they have a model that supports the features I want. For example I purchased Gigabytes ultra durable brand boards and the first one lasted a year, the second one which was a different model lasted only 6 months. I know Gigabyte is a great brand and all but to hell with luck which is something I don't have with MOBO's.
It's one of the few products out there that I do consider brand as of any real importance. Refrigerators are another as well as A/C window units, chainsaws, tools, work boots and a few other things.
