I think it comes from practical experience of these models being complicated to use rather than any theoretical argument. I've never used hierarchical or networks database but I understand people who did found relational database much easier to use and develop.

The old-style databases must have been theoretically correct at some level otherwise no-one would have used them if they were costantly giving wrong results.
