I think that a clear difference is that Property Tree is intended to support I/O of configuration settings, and of other kinds of human-readable data files. I could well envision an application that uses both libs: program_options to handle command-line parameters, and ptree as a storage format for its data files. I agree with many of your other points. In particular ptree could be made leaner, and the double-indexing may well be overkill (I haven't looked at the implementation itself). But the needs the library seeks to address are very real.
