Work on late-80s and early 90s Bianchi road bikes with 27 x 1 1/4 wheels compromised of Sansin hubs, Araya rims and Italian stainless steel spokes much Hillrider? The rear (on the yellow model I built a few of) was nutted while the front was QR. They were decent wheels.
My point once again is: There are just too many exceptions to use "nutted axles" as a criteria for determining "lower quality" wheel.
There are better and more reliable criteria that can be used without having to take apart the hub.
Also should note that there was one line of bikes I worked on in the 90s that had rear Shimano STX hubs with nutted axles. Was rather surprising cause normally that was found in Altus/Alivio/Exage. Can't remember if it was GT, Bianchi, Mongoose or some other brand.
The STX was a decent hub - not low quality in my opinion.
