LibreOffice is not fully compatible with Microsoft formats as OnlyOffice is, yet it's good to to be protected from Microsoft Corporation's vendor lock-in.

Does most things you'd want MS office to do, however, some formatting options aren't available in office files (.docx, .pptx, .xlsx etc). If your main focus is using these files, this is probably not for you, but for anyone else, it is perfect.

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.

It's much faster than Microsoft Office, it's compatible with MSO, can do the same, and it's free. I have tried several MSO alternatives, and OnlyOffice is by far the best.

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

Apache Open Office is based on the old StarOffice, which 10-15 years ago was way ahead of MS Office - and so is AOO to-day. The other alternative is LibreOffice, which is also based upon the same old platform. Those two are especially efficient for work, but also fill any need a private user can have

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)
