I can organize related windows by task, so if I have two things going on which both involve say a Finder window, a Safari window, and some other assorted things, I can switch between tasks as a group with one gesture instead of cmd-tab which will pull up both Safari windows or both Finder windows, and then maybe needing to cmd=` to switch to the correct one.

When I'm in the appropriate space with only those related windows, the exposé gestures are also much more usable than when everything is jumbled together.
