KDE has always supported as many task bars as you want, Windows you limited to 1 task bar or 1 task bar per monitor in win8, and it is very limited, KDE you can have 2,3,4 or more taskbars on every monitor and can put anything you want in them Gnome2 was similar. Gnome3 does not have a taskbar at all, there is a extension that kinda creates it but the work flow for Gnome3 is taskbar-less, but the biggest problem with Gnome3 is there is a bug that has been there for a LONG time when you have stacked monitors the window manger gets all screwed up, so you can only have monitors configured in a strait horizontal configuration. Cinnamon only supports a single taskbar which is one of my biggest complaints with cinnamon Unity I believe is single only as well, but I have very limited exposure to ubuntu desktop
