Same here. If you need it occasionally for personal use it's fine. But as soon as you need to swap documents with other people on a regular basis it just doesn't work, as there is just a bazillion ways in which it will not render MSO documents properly and it will drive both sides mad.

As long as it's just a "a document" that's consisting of headlines, paragraphs and bullet points it might not matter, but anything involving more advanced formatting, even just formal letter will usually look bad once loaded in LibreOffice, unfortunately.
