One potential advantage of using Adobe vs. direct-to-PDF, at least for
big installations: with Adobe's LifeCycle server, you can configure it
to automatically generate PDF files with commenting enabled, which lets
anyone with the free Reader software add comments to the PDF's. (Without
this enabled, only users with a paid version of Acrobat can add
comments.) AFAIK, this is the only way to enable commenting by default
in your PDF files*. You can't do it with any desktop version of
Distiller, and you can't do it with any non-Adobe product--including
PE's direct-to-PDF feature.

* You can enable this with Acrobat Professional (desktop) on a
file-by-file basis, but it's a manual process that must be applied to
each and every PDF you want to enable for commenting.
