Rene,

lightdm and gdm are display managers, not desktops. The most visible
difference between the two are the login prompt for your desktop and
the way sessions are selected. lightdm uses fewer resources than gdm,
with gdm really being a thinned-down version of gnome shell. Once
you're past the login and session selection, then your desktop is
handled by the window, desktop and session managers.

I use XFCE, so my actual desktop is handled by xfwm4 (the window
manager), xfce4-session (the session manager) and xfdesktop (the
desktop manager). If you're running gnome, then I'd suggest staying
with gdm as it does offer some underlying support for the Gnome
desktop and may help Gnome start faster, but for XFCE and Mate, I'd
recommend using lightdm.
