It adds tiling to floating window managers like openbox, xfwm, and kwin, giving tiling to more mainstream desktop environments like GNOME, XFCE, and KDE. It's not really made for i3 users I think. I guess the advantage over i3 would be that those desktop environments have better integration with certain apps and a coherent look and feel. For example, on Ubuntu, which uses a modified GNOME, you can add tiling while still enjoying stuff like the volume control widget, gnome-control-center, consistent file open dialogs, and so on.
