The highest quality machines will probably be the business class machines made by Dell and Lenovo. They can be pretty expensive though.
Asus, Toshiba, Apple, Sony are generally at the top of the list in reliability ratings. The last such article I read was about 2 years ago, maybe you could find a more recent study.
I think Apple products are high quality, but they are also expensive and may not have the same features as basic models from other manufacturers.
