On my work Mac, I have Libreoffice and Neooffice. However, I needed neooffice on my Mac to open old Word Perfect files (WP) because my agency switched to Word several years ago and the older versions of Word did open WP however, recent versions do not and at the time, OpenOffice did not while NeoOffice did. Libreoffice has that functionality though, so now NeoOffice is redundant. Ps. Printing is fine with my Libreoffice.
