You're right. It's an oversimplification I made there. I recently tried MacOS in a VM and I talked a bit to people. You usually get a really smooth desktop experience. Apps are sandboxed, there is a fine permission system, they keep their stuff together and don't spread them across the filesystem. I think(?) the software brings their libraries along? Usually a used Macbook Pro is still fine and runs fast after 6 years. I think MacOS really shines on the desktop.

On Linux it's a bit more diverse. I mean we have the XDG specification file locations. But there's also lots of 'grown' stuff. We're still working on the sandboxing. And you get a different experience depending on the distro you're trying. And I'd prefer Linux on a server every time. It really excels for that use case and on the server we have Linux > everything else. And as a matter of fact I personally also prefer Linux on the desktop. And my Debian is also still running perfectly 6 years after I initially installed it. Had some minor issues with NVidia during the times, but that's to be expected and it wasn't that hard to fix. I wouldn't have had issues had I not mixed in testing and unstable, but there are lots of guides and tutorials around for the common woes. Which makes my argument a full circle.
