I try using Org-mode/Latex with pandoc, but end up using only Office for docx and PowerPoint.
OnlyOffice, I think it has the most polished UI and the LanguageTool plugin is really handy
Libre Office user for over a decade, recently moved to OnlyOffice and liking it a lot so far. Seems to do better with MS formats than LibreOffice, snappy and responsive. UI is cleaner IMO.
Libre is still good though.
LibreOffice, since I’m a light user and it’s usually available.
OnlyOffice. FOSS, great MS compatibility, more modern than LibreOffice, local apps and runs in web with Nextcloud with great document collaboration options.
Usually OnlyOffice though I keep LibreOffice installed as a backup as sometimes I’ve had weird compatibility issues with the former (very few and far between but still)
I’d say 95% Markdown + Pandoc for when I make documents. The other 5% is LibreOffice.
When it comes time to make graphs and charts I really like wasting my time so I always try out something new (or old) to get the job done. Last time I used Pygal.
When it comes to dealing with docs from colleagues, it is all LibreOffice and Zathura.
