It felt less taped together (in the UI sense, anyway) before Windows 8, honestly. Mainly because they didn't do semiannual or annual (or whatever the schedule is now) feature updates.
Windows 8 was... Windows 8.
Windows 10 never felt finished, especially whenever they shifted the UI design between updates. Some things would follow the new look, while others wouldn't.
And now they're repeating that with Windows 11.
Yeah, it definitely wasn't perfect, but I was primarily focusing on the UI since that's what the others in this thread were focusing on.
