I use LibreOffice in my engineering practice. Even when exchanging documents with lawyers and other clients, containing extensive change tracking and comments, none of us had difficulties on any side of the exchange. At one point I had to update to a more recent version to access the "resolve comment" feature, but that was about it. (Random additional comment: One thing I especially like about LibreOffice Calc over Excel is its process for importing CSV files).
