I try using Org-mode/Latex with pandoc, but end up using only Office for docx and PowerPoint.
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.
I was using LibreOffice on everything but for some unknown reason it just flat out stopped working on my machine so I installed OnlyOffice and honestly I much prefer it.
What makes you prefer OnlyOffice over LibreOffice? I like how OnlyOffice seems to decrease possible format errors, so I tend to open docs in it after putting them together in Libre.
