I have a Tuf Gaming build which was my first in many years. Specs sounded okay but support was miserable. Basically one year of support and a BIOS update to support Windows 11 but lots of bugs not fixed. Tuf Gaming is one of their low-end boards. I think that Pro Art is in their mid-range, similar to the MSI Tomahawk. Then you get the RoG Strix at the high-end.
I suspect that they will eventually fix the RAM bug you saw. Functionality is one aspect of what you get for more expensive motherboards with ASUS but support is as well. If you want the best support down the road, you get the more expensive motherboards. We have an ASUS laptop from many years ago and there's a major bug in the cooling system such that the fans run full-blast most of the time. Even when nothing is running. It would have required a minor hardware fix and Asus just did nothing. So we went with an MSI system and it has been great. So Asus is off our list these days. I did look at the ProArt 13 and ProArt 16 this past spring and summer as they are considered very capable laptops with a lot of nice features.
Then there are the Gamers' Nexus videos:
ASUS Scammed Us
The ASUS Dumpster Fire
Confronting ASUS Face-to-Face
So what I've seen and researched is a thing. I think that any vendor can have a bad run and it's okay if they fix it but their reputation will take a hit and winning it back is difficult.
