Certainly if you don't like the modern "ribbon" interfaces of Ms Office you'll love LibreOffice /OpenOffice, it doesn't have all that. Basically unless you need the very advanced features like Visual Basic etc it's better in a lot of ways. Trt it, if you don't like get rid, costs nothing!
Main thing stopping it being widely adopted is lack of a full featured email client like Outlook with group calendars, integration with Lync etc, but for home use that's not an issue.
