Bios Magazine posted a review on the Nuance PDF Converter Professional 5

If you work in an environment that relies on PDF documents as much as it does on Microsoft's Office, Nuance's PDF Converter Professional 5 is a much better value proposition compared to Adobe's Acrobat. And while there are plenty of free Web services that convert documents into PDFs, Nuance PDF Converter Pro 5 is a great all-rounder that offers advanced features such as digital signature support, side-by-side PDF-file comparisons, form creation, and PDF archiving of Outlook e-mail. It's extremely easy to use (there's even an optional assistant) and it handles images, links, and tables impressively. The only issue we had with it was that every once in a while an image shifted during conversion and was superimposed over the text following it. Overall it's a very impressive package
