I don’t think it’s a question that Linux has more jank. I recently installed a fedora spin on a laptop that came with regular Fedora installed originally and the WiFi didn’t work. That’s some janky stuff right there.
I've also had registry corruptions, and I've had unprompted updates brick my hard drive because Windows Update is a terrible piece of software, because as far as I can tell the Windows "repair tools" have never worked for any human in history, and neither has System Restore.
I've had updates in Linux break things but never so thoroughly as the time my mom got an automatic update where she literally could not boot in at all (because I think that the automatic update to Windows 11 that she did not want or ask for screwed up the boot keys).
On the other hand, Linux doesn't try to copy my home directory to RedHat's cloud, or force some AI assistant that I don't want onto me.
Installing the equivalent of OS "slop" isn't Linux's fault... For better or worse the choice that is afforded by OSS licenses means that many of those choices will be bad.
