XP really was the last "golden OS" with a real "user experience". This is the last OS in which you could completely disable the page file and work only from RAM with excellent response. This is the last OS where the system latency was an order of magnitude lower than that of subsequent versions. That is why the sound engineers loved it so much and sat on it until the very end.
W8.1 was simply a polished W7, but it had one extremely negative drawback, which, to the sadness of all professionals, migrated to W10-11 - the lack of a classic theme with compact window control buttons. In W7 this topic was still there, but the vile M$ deliberately disabled V-Sync in this topic, which supposedly worked in browsers in the Aero theme (I personally checked this statement and V-Sync does not work in W7 there either). I didn't care much about the tiles - all this can be easily removed, but there is no way to return the classic theme without a patch of system DLLs in W8-11 for the most compact (packed) interface on the same screen resolution in comparison with W7 and older ones.
Another interesting point about W10 vs W11 - without any patch of system DLLs in W11 you can return the beautiful analog clock of W7, but this is not possible in W10. Apparently M$ deliberately returned this as a setting in order to somehow lure users away from W10.
This fall, W11 LTSC is finally being released, which means that M$ is finally confident that it has at least some kind of stable kernel for the enterprise version with a long-term (5+ years) service channel. Let me remind you that the W10 LTSB came out a year later in 2016.
The funny thing is that W11 is essentially destined for the same fate as W8.1 - it is a pass-through OS in front of W12 (in which obviously user spying tools from M$ will reach new heights).
I would love to use LTSB, but the new drivers do not support it and there is no support for VP9/AV1 hardware decoders, or rather wrappers with VLD video driver decoders for browsers.
In addition, as I already wrote in LTSC 1809, Google deliberately disabled support for the old VP9/AV1 hardware decoding method, which worked until about version 100 of Chrome, as I discovered. I was never able to return VP9 hardware acceleration under LTSC 1809, although I installed the latest versions of the VP9 wrapper from the M$ store. In LTSC 2021, everything already works as before, even with the same old video drivers from 2020. But LTSC 2021 is even worse than 1809 and it only has 5 years of support, in contrast to 10 years of 1809. So, LTSC 1809 lovers are already being slowly smoked out by such vile methods to LTSC 2021 or W11 LTSC 2024.
You can recall other disadvantages and advantages of each version, but it will take a long time to write. And no one knows 100% of all the problems.
In any case, the new hardware will force everyone to switch first to W11 and then to W12, even if the idiotic neural networks didn't give in to you in vain. Or go to Linux and constantly wait for years for support for current hardware and constantly struggle with a hellish mess and a complete lack of responsibility in a team consisting of "a swan, a crayfish and a pike."
