Windows 7 with Aero Glass, in my opinion, was the last version of windows that actually felt warm and comfortable to use. 8, 10 and 11 all feel so cold, sterile and boring.
I’m with you there. Maybe all the gray was off putting to people, but I liked that the ui elements were more visually distinct from the content without being overly elaborate and distracting.
These days, my daily driver is a gnome desktop on Linux, and it gets the balance right without looking dated, imo.
My personal daily driver laptop is also running gnome, I much prefer Wayland gnome then much of anything else. My work and personal desktop are Win 11 for AutoCAD and gaming reasons.
While I don't love the inserted ads in 11, we use corporate at work which doesn't have them but I can still customise it with a pride vibe. Quite enjoying it this way.
