I’ve been using libreoffice for several years, and when I have to cowork with someone, compatibility issues always happen. However, since last year, I’ve been experimenting transitioning to onlyoffice for a few academic works, and it has been so smooth. So far, I opened all documents people sent me without issues, and published some works, and no one involved in the process complained about anything. If you need compatibility with ms office, I suggest using onlyoffice. It’s also foss and can be used at most OSes, even on android.
