I disagree. On my laptop running Windows 11, the edges of context menus are horribly pixelated because of the round corners they've added. Maybe there's a setting to fix that but I shouldn't need to look for that after I hit the "update to Windows 11" button.

This is something GNOME does better for God's sake and they can't even show thumbnails in a file picker!

I'd say Windows is selectively polished. Some parts are worked out beautifully while others are hacked together. macOS is a lot better in terms of polish (but a lot worse in many other aspects).
