Pro Free and open source
Pro Comprehensive suite of applications
LibreOffice includes applications for word-processing, spreadsheets, presentations, and database management.
All major operating systems are supported, including Microsoft Windows, Mac OS X and GNU/Linux (Arch, Fedora, Mandriva, Debian, Ubuntu, Suse).
It is available in more than 110 languages.
Pro Font embedding support
Font embedding ensures that the document will display correctly whether or not the target machine has that specific font installed.
Pro LibreOffice can take from OpenOffice, but not the other way around
Due to licensing each office suite uses, only a one-way transfer of code is possible, offering more long-term potential for LibreOffice over OpenOffice.
Pro Portable version
LibreOffice offers a version of the suite that does not require installation. It can be kept on a thumb stick to ensure that you have an office suite on whichever machine you choose to use.
Pro Encryption support
LibreOffice allows encrypting and password-locking files.
Pro Presentations can have 3D models embeded within them
Impress supports 3D models in gITF format.
Con Track Changes needs to be improved
Collaborating on a single document is difficult. Track Changes makes the document hard to read as both edited and deleted text is displayed, it's not possible to print comments, tracked differences between document versions are sub-optimal and there's no system for accepting/rejecting changes.
