don't forget that Asus are a big company and as such are statistically more likely to suffer product failures. Their rma process isn't always the best. Only had to rma a couple of Asus products swift monitor - courier messed up and swapped the 144Mhz one for a 60hz/4k swift! Not Asus' fault and quickly sorted with an acceptable product swapped over. Also a 480gtx years ago- took a while to sort out, about a month with gpu needing to sent of to their then sister company pegatron (Asus + pegatron = Pegasus... Someone liked mythical creatures)
