    ONLYOFFICE vs LibreOffice Comments

    ONLYOFFICE is less functional than Libre Office, but it is open source and has the following advantage I find useful: It opens all Microsoft Office .doc and .docx files with better fidelity than Libre Office does. Especially those with embedded vector graphics, which Libre sometimes screws up. The functionality is more like Google docs or something (e.g. no plugins, etc.). But it's good to have around.

    Onlyoffice is realy promising and amazing piece of software. However, I find it to work really bad in (poor) machines with less RAM (4gb or less). Optimization is way worse than what a software with maturity as LibreOffice can get. Also, like what other people said here, LibreOffice have more features at all, it's a more mature and reliable project.

    I like ONLY Office for simplicity and compatibility with Microsoft Document but if you need more functionnality Libre Office is a better choice.

    OpenOffice seems to be end-of-life. It doesn't receive as many code contributions as LibreOffice and has fewer features. LibreOffice is a successor to this project and is probably better for most users.

    Oracle totally squandered this project after they bought Sun. By the time they handed it off to Apache it was too little, too late, and most of the active work had moved over to LibreOffice. Apache's basically kept it on life support for the last decade.
