25 years ago Asus sold only OEM mobos and they were top quality. Since deciding to go to the retail consumer market where profits are much higher, Asus has rushed a lot of products to market that could be accurately described as half-baked. While Asus makes sure that they get good hardware website reviews... owner's experiences do not always match the reviewer site's results, as noted countless times.
In my experience of several decades of building performance PCs, Asus mobos tend to be sensitive to the RAM used even if it's on the QVL list. This can make for many a headache for end users. I personally would like to see Asus invest more effort in designing their mobos and BIOS so that they work reliably without issues because it's a royal PITA to troubleshoot Asus mobo issues for them when they should have corrected these issues prior to shipment of the mobos.
It's also worth noting at least in the U.S., Asus's Tech Support (sic), is a fantasy at best from my firsthand experience. Many people get so frustrated with the lack of Asus customer support that they buy a different brand of mobo and just take the financial loss on the Asus mobo as it's more headaches than it's worth dealing with Asus customer service (sic), in the U.S. I can state that IME most of the mobo makers customer/tech support in the U.S. is woeful to say the least but Asus's is infuriating at best. All the mobo makers need to improve in this area.
