If this generates enough interest I'll add a page to piratealts.com that is automatically updated each day or week. I guess it would also be interesting to extract this data for Amazon Prime as well. Also, suggestions to improve or add data are welcome using the comments section below or email.

Most of the data is not surprising, Netflix has more movies, Hulu has more TV shows. A couple of noteworthy points are that it looks like Netflix is more committed to HD content and that Hulu has a higher percentage of new movies (from 2012) relative to the catalog size.
