LibreOffice is free and open source and also brings in free document types which are not restricted by Microsoft.

Libreoffice lacks in some point of support Microsoft only document styles but you can create fully functional documents shareable with any Microsoft office Suit.

It's free and open source software. Compatible with most Microsoft Office documents. Doesn't track you at all.

In my opinion WPS gives you the closest thing to MS Office. If you are familiar with MS Office you should be able to use WPS right away. This is the main reason I prefer it to OpenOffice or Libre Office

Don't use it! Apache OpenOffice is a dead project. For many years there's been no real serious updates to the project.

OpenOffice was a great alternative when it was in really active development. But for more than a decade it stands on the same place without meaningful movement and it is very unfortunate. Rather use LibreOffice, which stands on the great legacy of OpenOffice but is in active development.

I was using only Libre Office for years on Linux. Now I use FreeOffice and Latex via VS Code the most. FreeOffice is fast and streamlined, the UI is well built and looks good, very compatible with MS proprietary formats. It's also available for several platforms. There's a commercial alternative with more features too if you need support. Just try it.

Calligra Suite's interface kinda resembles iWork (is it still called that?), which would come as a shock to those coming from Office. Unfortunately, I didn't have a stable experience using it on my device running Zorin OS. It also lacks collaborative features.

It does not require DotNet or Java to run. It runs natively on all WIN32 systems. That means it can be installed and run on Windows 95 right up to Windows 10 without any problems. It supports only open document formats, like the Rich Text format (*.RTF), that can be opened by any office suite on any operating system without any formatting errors. It is a very small download and install and also does not use any resources from the system.
