Classic Windows (95-7) was the best era for Windows and always will be the best in terms of GUI. Everything that came after 7 has been a downgrade from 7's GUI.

If you run emulated Windows 98 in the browser with e.g. v86, it is faster to open the start menu on the emulated Windows 98 than on the real Windows 11 running it. Windows user experience really went downhill after 7.
