I still don't really know what you mean. How a document looks like depends on you. I've got very many fonts available, much more than average Microsoft Office user has. And it's easier to use LibreOffice from my point of view, because it emphasizes structure. It looks much cleaner by default than MS Word. The only thing MS Word is better in is typesetting. LibreOffice simply fails to place letters properly.

Documents produced by office suites are not really good for publications. They are very annoying to handle, no matter if it's MS Office or Libre. The cheapest option to have something professional is LaTeX.
