LinuxQuestions.org - 1 taskbar vs 2 taskbars desktop environments in Linux distros

I prefer "1 taskbar" desktop environments before "2 taskbars" desktop environments because it's better to have everything in one "line" instead of one taskbar at the top, one taskbar/dock on the left or at the bottom.

So, I have a hard time to understand why would people use Unity or even Gnome 2. Not talking about the many mac-dock-like widgets, etc. My top desktop environments are KDE, Cinnamon, Windows10's - or even the old win 7 is quite good - eventhough it's much harder to customize Windows taskbar than linux DE taskbars.

And I absolutely hate Mac, even more than Unity, because in Unity you at least don't have the "empty ears" around the dock like here http://apple.stackexchange.com/quest...of-the-screen/ .

There are many things that Windows did wrong, but the start menu, opened apps and notification area in 1 taskbar is something that should be given credit for.

In my opinion and experience it's more productive than the Macintosh-way. especially when multitasking.

So, if you are not using the classic windows-like task bar in Linux, what is your reasoning. I am interested in that very much.

I am mostly interested in opinions of users of the 2 or more taskbars on one desktop with the classic windows managers and even tiling window managers like awesome, xmonad or i3 and what is the reason why you use more than 1 taskbar.
