I'm already on Windows 11 (21H2).
I've never had any issues with this version (unlike Windows 10, which was very problematic at launch). The settings panel is perfect on W11, and the OS is more responsive.
However, some QoL features are missing because I'm still on the 2021 version. I decided to block any updates when 22H2 was released because, after my machine was updated, everything got worse. It became slower at boot, virtualization broke, and some apps wouldn't launch. I don't want to do a clean install every year. New Windows builds are still a nightmare when they force you to update.
The start bar is not bad and clean, unlike the mess we had with W10 (crap Metro). I'm still using a third-party app on my desktop (StartAllBack), but I leave the vanilla start bar on my laptop. (I like folders and minimalist design)
I still think Windows 11 21H2 is "perfect" for a modern Windows OS. The only problem is when Microsoft tries to install too much bloatware like Edge and Copilot (also on W10). I've already blocked all the spyware/telemetry crap.
The only issue with Windows (since 10) is that the AppData folder keeps getting bigger and bigger, presumably for security reasons. Now it's almost 100GB+. WTF.
So, in almost four years, I've never done a clean install on my PC (except for the 22H2 incident; I just used system restore) and my OS is still running great. I run Baldur's Gate 3 and Stable Diffusion without issues. (Python/CUDA installed). I got a new GPU (4060Ti 16GB) and it's working with no issues at all when installed.
But what Microsoft announced with Copilot+ and the new "Recall" system looks like a nightmare for privacy.
So my choice is to stay on 21H2. But if Microsoft somehow blocks the lifecycle of my W11 version (making Steam or software incompatible), then yeah, I think I'm going to leave Windows for Linux.
