Specifically what registry issues have you had? What update slow downs have you experienced? What OS corruptions have you encountered?
I had updates break parts of the registry, causing explorer to act up (can't remember details now but it caused loads of popup warnings). Only obscure tips after a lot of googling resolved that one - had to extract some part of my backup and inject it I think. I had cumulative updates cause system slowdowns and incompatibilities with standard applications (Photoshop most prominently, getting very slow and crashed easily in a virtual desktop environment).
Only discovered how bad it had gotten after a few years of updates when Windows finally got corrupted (GPU no longer recognized - no cleaning and reinstalling of drivers helped) and I had to resort to my original installation clone. Suddenly the computer was flying and apps were fixed.
Suffice to say - I don't update anymore, it's all disabled forr good. They can keep their 'patches'. Been trouble-free ever since.
There were more issues over the years of course but that was in previous versions of Windows. Plenty of reinstalls before I got really conservative with this OS, stopped installing trialware, always kept a bootable clone, etc.
In comparison I have never in my 12 years of macOS experience so far had to resort to reinstalling the OS. Even the more resilient leftovers from deinstalled apps I was able to remove without compromising system stability. I install and remove trials all the time and generally just use the system without thinking twice. Night and day difference to my Windows usage.
Also issues like failing drives were easy to debug thanks to the logfiles. That was much easier in the old pre-Sierra system of log files though. Sifting through the current day console output is not exactly enlightening to me.
