Regarding file sizes, I ran some tests, and the results were surprising. For these tests I set "Use file compression" to ON in the Preferences. I loaded V4, and then INJ Morphs++ V4.pz2. When I saved that figure with "Use binary morph targets" OFF I got a single CRZ file of 10,481 KB. When I saved it with "Use binary morph targets" ON, I got a CRZ file of 495 KB and a PMD file of 16,746 KB or a total of 17,241. Much bigger!

So if you are using file compression you end up with LARGER files by going with PMDs. I know that PMDs aren't just compressed files, and I assume that they are optimized for Poser, so perhaps a CR2 or CRZ file has to be reformatted within Poser which would add to the load time and result in similar sizes of data inside of Poser.

Still, I remain puzzled as to the advantage of PMDs.
