LibreOffice does basically everything you can do in Microsoft, and it's open source and doesn't constantly try to call home.

Plus, LibreOffice is free.

Unless you need Microsoft Access, LibreOffice is the perfect drop-in replacement for whatever you already do with Microsoft Office.

If you are okay with NOT working with Microsoft Office Open XML (OOXML), LibreOffice might get the job done. But sadly, we do need to use Microsoft Office Open XML (OOXML) files (generated by someone else). LibreOffice is not good for this (at least at the moment)

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

This office suite provides the best compatibility with Microsoft Office. The lifetime licence is a good investment. You can switch the user interface from menus to ribbons.

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.

Easily the easist, fastest & best designed MS Office alternative, though it may lack some advanced functionality (I wouldn't know, as I primarily use it for standard, basic office suite use)
