I just like that it allows you to capture extra detail in your morphs.  I like to do bundles of character head morphs, but I'd been limited in the detail I could capture in them, and if I wanted to add that detail with bump or displacement mapping, I'd start to complicate the product and make it more difficult for the average user to use the textures they'd like in companion to the morphs.
