The latest edition, LibreOffice 6.3, is better than ever. It may also be your best choice for a standalone desktop office suite in the years to come. You see, Microsoft doesn't want you to buy its next office suite: Office 2019.
Jared Spataro, corporate vice president for Microsoft 365's blog, The Twin Challenge, showed Office 365 crushing Office 2019 because it "keeps getting better over time, with new capabilities delivered every month, while "Office 2019 apps are 'frozen in time.'" "They don't ever get updated with new features, and they're not cloud-connected," he added.
Of course with a cloud subscription you don't own anything except a period of use, you stop paying, you don't use it, and you will keep on paying along with annual increases.
LibreOffice will install on various OSs for free and if you need to sync docs you can use Dropbox, NextCloud, etc.
If you want a standalone office suite for your computer, LibreOffice may soon not just be your best choice, it will be close to your only PC-based choice.
