LibreOffice is really good nowadays, as is GoogleDocs.
Contrary to that is M$ Office which is on steady decline in usability and stability ever since Office 2010. Office 2013 and 2016 are a big pile of ugly as hell unstable crap.
Office 97 was already feature-complete, almost nothing new got introduced with 2000, 2003 and 2007 only brought the instant-preview and the new toolbar. With the new toolbar people just found out about many former not so well known features, that had been introduced back with 95 and 97, and thought it was something new.
Without the big budget global bribery in public sector, schools and big co, M$ Office usage would fall off dramatically within years.
It's such a shame that ContentEditable, the inbuilt WYSIWYG HTML editor, in the HTML4/5 spec has never been improved. I blame it to M$, Google and Apple, the browser cartel, they actively prevent web competition by not fixing years old well known ContentEditable "bugs". Otherwise, GoogleDocs, Office365WordWeb, iCloudPages would be dead products in the water, as everyone could just use the ContentEditable.
