sounds about right aligning with my own experiences over about 18-20 years of the brand. they haven't changed a lot since their divesture from asus but they're about the same. calling it a divesture is an over statement. they both dropped using pegatron as a manufacturer around 11 years ago dunno about the quality differences before or after, asus have always been good to me. they said they were gonna use ecs compal and other odms back then. if you've been in the diy space for a long time you'll know ecs is a terrible company. couldn't tell you who the main odm is now and for what ranges.AsRock is YMMV.
My board is about 12 years old and hasn't had major problems, but it was defective because the headphone jack is screwed up. Doesn't make a reliable connection and might be crossed up with a different port. Not worth a RMA at the time.
