Alternatives to GNOME
Use a Linux desktop organized around an activities overview and workspaces. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original

Replacements
Listings that take over the same core job as GNOME.

Xfce
Use a modular desktop environment built around traditional panels and windows.

COSMIC

Also worth comparing
These listings name GNOME as their own alternative, so the relationship runs both ways.
Enlightenment
A window manager, compositor and minimal desktop for Linux, BSD and other UNIX systems.
GNOME organises the desktop around an activities overview and workspaces with consistent settings, though shell extensions must match the installed version.
LXQt
A lightweight, modular Qt-based desktop environment for Linux and BSD with X11 and Wayland sessions.
GNOME organises the desktop around an activities overview and workspaces with integrated settings, and is heavier than LXQt with version-matched extensions.
