> The math equations made by Word have a distinctive appearance.

Try and use the GUST fonts (http://www.gust.org.pl/projects/e-foundry), Microsoft Word equations will look then excellently made. The last time I used the GUST fonts, by the way, I was able to export Word documents to pdf only be printing, as using the pdf converter some glyphs would "lose pieces"; and exporting via printing I would lose the clickable links. But I did not try with the Word plugin for the latest versions of Acrobat.
