I realize that Google needs text to understand the content of pages, but pdf files are prettier and more official looking.
Major search engines can read pdf text just fine-- unless the files involved are archaic low-budget pdfs that render everything as an image. In which case you've got one more reason to link to the html version. This in turn presumably has a link to the pdf if someone wants it.
