Ever since the inception of GNOME and KDE there has been confusion among new Linux users which is which and which is best to use. The former question is fairly simple to answer. The latter question, however, is a bit more complex due to user-specific needs/wants.
With that in mind let us begin by illustrating the differences between a desktop environment and a window manager. We'll begin by showing how the Linux graphical desktop is layered.
As you can see, in the image below, there are basically three layers that can be included in the Linux desktop:
A Desktop Environment generally includes a suite of applications that are tightly integrated so that all applications are aware of one another. A Desktop Manager will also include some form of panel that includes a system tray where small widgets can be placed for quick action or information.
Much of the confusion starts to peek out when you examine such Window Managers as E17 (Enlightenment 17).
The most recent iteratio of Enlightenment includes many of the elements usually found only Desktop Environments even though Enlightenment is still considered a Window Manager. To this point I generally refer to such desktops as Desktop Managers.
There are two main Desktop Environments: GNOME and KDE. If you are curious as to which is right for you, here is some advice. The latest default GNOME will make users of OS X feel right at home, KDE 3.x will make Windows XP users feel at home, and KDE 4.x will make Windows Vista users feel at home.
As to which Window Manager is best suited for which user? Since there are so many Window Managers I will highlight my favorites.
One of the most wonderful things about the Linux desktop is that it is only limited to your imagination. You can make the Linux desktop look and feel exactly how you want it. You can go from complete minimalism to the full-blown 3D goodness of Compiz-Fusion. I will give you one warning: Playing with the Linux desktop might be as much of a time-suck as World of Warcraft.
