I was able to make a composite wall in one "pln" file and load it via Attribute Manager into another "pln" file and it works correctly. So I guess I shouldn't save to the favorite "prf" file because I could not load any file with that extension from attribute manager.
PRF files are loaded from the Favorites palette.
AAT (attribute) files - as well as the attributes of existing project files (pln, etc) are loaded from Attribute Manager.
Favorites are sort of like recipes where attributes are the ingredients. As you found originally, loading a favorite into a new file did not give you the new composite. That's because the Favorite merely said it wanted to USE the composite. The recipe was there, but not the ingredients.
Loading the attributes gives your the composite in a new file. But, there are times when you might still want your Favorite. As a 'recipe', you can have dozens of Favorites that all refer to that same composite - the Favorite will record (optionally) the layer, the wall height, the reference line offset and many other characteristics of the Wall Tool so that you can pre-load those settings for a particular wall.
Hope that helps to sort out the difference between the two.
