Demo and feature list of PDF Exporter?

I am considering a Confluence solution for my client that requires good PDF export.  I need to demonstrate this to them.  Where can I find

-- A simple list of the features of the PDF exporter that make it better than the native Confluence export? I did find the brief presentation at the top of the page, which gave me a basic idea.  A product comparison list would be good, though.

-- A publicly available on-line example showing a Confluence wiki and the resulting PDF made using your product?

My apologies if these things are staring me in the face.  I did look around your site and the listing in the Atlassian site but have not been able to locate them.
