Best practice for symbolizing multiple polygon layers

One of the most frequent issues I deal with in my maps is deciding how best to symbolize multiple overlapping polygon themes (such as municipalities overlaid by zoning classification). It often becomes too complex and confusing to identify features. I was wondering if there is a good rule of thumb to use when doing this. Thanks!

Mapping Center Answer:

This is too open ended. Please ask again, but specify whether you've got lots polygons that overlap, whether the overlap is substantial, whether there are many polygons stacked in the same location, etc.

That would imply one answer, which is that there really isn't a rule of thumb.  But generally speaking the more complex your scenario, the more like raster processing you should think of it.
