> OnlyOffice seems to be the only FOSS office suite that handles Microsoft Office documents correctly. I remember also looking at WPS Office for this and it seemed mostly okay to me: https://www.wps.com/office/ https://www.wps.com/office/ (though no source code available, at least it doesn't seem so) Then again, LibreOffice feels like the most trustworthy option out there for me (and is the default in many Linux distros), so I ended up just using that, any drawbacks and all. Nowadays I use LibreOffice on all my computers and have basically gotten rid of MS Office altogether. If I ever need to send someone something that looks consistent across all devices, there's PDF/A. I've actually used PDFs for presentations as well with no issues, especially after the inconsistencies of LibreOffice Impress and PowerPoint made one of my past presentations look like an utter mess on someone else's computer (fonts/locations were all wrong).
