GNOME is one of the most widely used desktop environments and is the default standard for many Linux distributions such as Ubuntu, Fedora, etc. The latest GNOME has a clean look & feel, window management features, and an app directory similar to macOS. Thus, developers who mainly use macOS can easily get used to it. Of course, GNOME3 is a full desktop environment, and running an OS which runs GNOME virtually on VM solutions requires high graphical processing abilities. On my M2 Max, there are no performance issues.
Unity is a GNOME-based desktop environment that originated from the default Ubuntu environment. It has a clean interface, a macOS-like menubar, and the window close button in the same position. The official development of Unity has been stopped since Ubuntu readopted GNOME3 as its default desktop environment, but community-driven development continues. As a result, a Unity-flavored version of Ubuntu, called ‘Ubuntu Unity’, is available.
Cinnamon is one of the most popular desktop environments for Linux distributions. The most characteristic feature of Cinnamon is "modern but traditional." Actually, Cinnamon is based on GNOME 3, which represents the modern era of GNOME history; however, Cinnamon inherits a look similar to GNOME 2.
