I second the Pages recommendation. Keynote is fantastic and Pages has much better typographic functionality than Word. I can immediately tell whether a document was produced using Word, or LibreOffice, because of poor ligatures and spacing. I think Numbers falls short of Excel, which is probably one of the best products Microsoft ever created. If you don't mind dealing with slightly antique UIs, both LyX and TeXmacs are WYSIWYG and can produce outstanding documents with little effort.
