I switched to LibreOffice more than a decade ago and I never missed Microsoft Office 🤷‍♀️

(EDIT: I don’t mean this dogmatically, there are plenty of times I have had to compromise and go back to proprietary software, but LibreOffice really has successfully replaced Microsoft Office for me - it’s just as feature-rich and reliable with a similar UI. Google Sheets has a few features that I like and which aren’t in LibreOffice or MS Office, but I only use that for work when I need a collaborative sheet.)
