GNOME. Been using Linux since before GNOME Shell was a thing and when it became a thing it just clicked for me. In my opinion, it’s by far the most polished DE and provides the most elegant and intuitive launcher and workspace switcher of any DE or OS I’ve used. At least they did, until they fucked it up by moving from vertical to horizontal workspaces and made the workspace previews so small you can no longer see what’s in them.

Which is the downside of GNOME. Sometimes their developers are their own worst enemies. Fortunately, there are usually extensions to fix the most egregious “enhancements”.
