Microsoft Office or LibreOffice: I have been using the LibreOffice Suite, an open source application, for a long time. It works well, is free, and does everything I need from an office suite.
The latest version, LibreOffice 6.3, seems to be the best ever.
You see, she Microsoft does not want to buy the next Office 2019.
Jared Spataro, vice president of the company on the Microsoft 365 blog, the Office 365 cannibalizes Office 2019 because "it is constantly improving with new features provided every month, while Office 2019 applications are never updated with new features and are not connected to the cloud"
On the other I also use Google Docs. But if I want an office suite that runs on my machine without an internet connection and without worrying that Google or Microsoft is reading what I write I choose LibreOffice.
Of course the choice is yours, however I should mention that the Latest version of LibreOffice is much faster in both opening and saving documents and spreadsheets.
The Document Foundation, the parent company of LibreOffice, claims to be a class faster than the previous version. I'm not sure, but the application is quite fast.
As always, LibreOffice supports Microsoft Office Open XML (OOXML) format. Thus it supports export to DOTX document templates and XLTX spreadsheet templates. It supports importing diagrams from DOCX drawingML, importing / exporting SmartArt from PowerPoint PPTX files and better manages XLSX Pivot tables. It's not perfect yet, but it 's approaching.
Exporting LibreOffice files as PDF has been improved. It now fully supports the PDF / A-2 document format. This is required by various organizations for long-term file storage. Also simplify the editable PDF formats by integrating the Form menu into LibreOffice Writer.
A new feature, which can be useful to businesses and all those who are interested in security, is that with the new version of LibreOffice allows you to "process" the hidden information contained in the documents. This way, you can completely remove or hide sensitive information before sharing the file.
LibreOffice runs on Linux, MacOS and Windows. You can also use LibreOffice Online as a Cloud Software-as-a-Service (SaaS) application, running it from a cloud you control.
So if you want an office suite that will be updated regularly with new features, try LibreOffice. Following Microsoft's decision to use only SaaS in the Office suite, LibreOffice may soon be your best choice even if you use Windows Office.
Of course, to be fair, we have to mention that Microsoft Office is a very advanced office suite. But it does cost (unless you are using a pirated copy), and I personally can not trust either Microsoft or Google.
