I think you may be applying your personal perspective here or rumors from anti-Win 11 people. I just checked and it looks like 24H2, while definitely introducing some bugs, as all updates do, has generally been cleaner than most. Notably, I have not seen widespread reports of any critical problems.
Most of my computers didn't even show 24H2 as available until late December, which suggests MS was taking their time with the update and only pushing it to hardware and software combinations that they had tested and appeared not to pose problems. I have only had issues with 24H2 that I know of on one system across many different computers: in the known issues list as "Camera use might cause some applications to become unresponsive," but in my case, the only impacted feature is Windows Hello, where it's not properly scanning and unlocking Windows on some HP laptops, but only after they've been running for many hours or days (which is probably why MS missed it). But also found an easy temporary fix:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows Media Foundation\Platform]
"EnableFrameServerMode"=dword:00000000
Have had no problems since adding that to the registry.
Here's the list of major regressions acknowledged by MS and their status in working through them:
