Which one is better: OpenOffice or LibreOffice?
Both applications are good, offer decent experience and Free.
Try both of them and pick which one you like most
Both application suites are very good and offer standard document and spreadsheet processing. However, one application has additional features than the other one and vice versa. You will have to install both of them to be sure which one is suitable for your business. My advice is to test both of them and then see which one has all the necessary features to match your requirements .
