For me it's that compared to windows and linux, handling multiple windows between screens is always problematic, and is made worse by alt-tab bringing up all the windows for an application, which means they pop up in the other monitors too which isn't usually what I want. Maximizing is usually not as straightforward as one would hope, and the dock moves to any window if you leave your pointer at the bottom which can get annoying fast. As some point out apparently there's 3rd party software that allows you to fix these issues, but that's not an option for me because I use a locked-down Mac for work and can't install 3rd party software, so I'm stuck with the annoying base behavior.
