I cannot speak for gp but I use tiling window managers when I use Linux. Usually they do not work so well with desktop environments, or it to much effort to get them to work properly.
The big advantage of tiling vms is that you always use the whole screen area without having to only use maximized windows. You can easily split the screen into several areas where you can put windows. Another advantage is that they are usually keyboard driven so that it is possible to launch, close and arrange windows without using the mouse.
The one I like best is wmii, which has a brilliant column system combined with tags instead of workspaces(i. e. a window can have several tags instead of only one workspace). Nowadays I use i3 since it is a bit more modern but so far I find that the usability is not quite as good.

It's strictly possible to do this in most non-tiling window managers. The key difference is that arranging windows with the keyboard is not just possible but significantly more practical.
xmonad works flawlessly with xfce. it's what keeps me from switching to any of the other tiling wms, though some of wmii's features do look pretty attractive.
