I'm never going to say one company is the best, and just blindly refuse to use anything else. But every Asus product I have owned has been miles ahead of the rest in terms of build quality and reliability. Asus graphics and motherboards are the gold standard. Sure there might be one or two other options depending on what you are building, but even if there are, they are just trying to match the standards that Asus has set. The first Asus product I bought was the Direct CuII r9 290x, and I immediately regretted every previous graphics card I have bought. The next computer I built had Asus motherboard and graphics, and that has been my go-to starting point ever since. I have had a few clients specifically request MSI, AsRock, and others. I will do it if that's what they want, but I don't recommend it, and the difference in quality is... Appearent, to say the least. Even when the feature set is comparable, the materials are often lower quality, the design is lacking, or some other corners have been cut. If you want the features, quality, and design all in one package, you almost have to get Asus.
