Honestly,I see no need for both. Fences is a great way to organize the shortcuts on your desktop. OD is a equally great way to organize your shortcuts if you don't like icons on the desktop at all or prefer to keep them all in one area, such as with a small display size.
. What the rig is used for often comes into play as well.In a work environment, Fences is a clear winner. On the other hand, OD is much more attractive when used with a matching WB, imho.
