Not true. LibreOffice has some serious bugs when working with doc, docx, & odt that are extremely problematic and have not been fixed for months on end. Exhibit A is the "read-error" bug when files have images.
This renders a word processor basically unusable. The solutions are either disabling autosave or not using images. I've been using OpenOffice for over a decade & I am this close to going back to MS Office. It used to be good. Post-fork, it's a piece of junk, & the community refuses to acknowledge this. Sticking our heads in the sand will not help.
