There are major differences in the design between Windows and Mac desktops, and generally speaking, Linux desktop environments function more like Windows than they do macOS.

The biggest difference is probably that under Windows-style environments, applications/processes and windows are mostly synonymous — each window represents an independent process in the task manager. In a Mac-style environment, applications can host multiple windows each, so for example even if you've got 7 Firefox windows open, there's only one host Firefox process. This is reflected in the UI, with macOS grouping windows by application in several difference places (as opposed to Windows, where that only happens in the taskbar if the user has it enabled).

"Windows style" also comes a number of other patterns, such as a taskbar instead and menubars attached to windows (as opposed to a dock and a single global, system-owned menubar under macOS).

"Mac style" comes with several subtleties that separate it from e.g. GNOME. Progressive disclosure is a big one. Where macOS will keep power user features slightly off to the side where they're accessible but unlikely to confuse non-technical users, GNOME just omits the functionality altogether. It also generally implies a greater level of system-level integration and cross-functionality from apps (including third party), lending to a more cohesive feel.
