XFCE for me, when my netbook was still alive.

I actualy liked Ubuntu's Unity, and the move to GNOME did not made me an happy user.

As someone that used Gtkmm during the GNOME 1.0 days, the way current GNOME works and the overuse of JavaScript made me look elsewhere.

XFCE was good enough for me (I am old enough to have used twm), and looks rather nice.

Hello, I am the other person who liked Unity. Now that we have met, the prophecy is fulfilled.

Seriously though, the fact that macOS still doesn't have an option to fully extend the dock horizontally or vertically drives me nuts. If you auto hide the dock it loses half of its value, and if you don't hide the dock then you have dead gaps in the corners that serve no purpose.
