You're not going to convince hardcore Office users (like me) that LibreOffice is good enough. I try it occasionally on my Linux laptop, and I have nothing good to say about it.

That's interesting, I have the opposite perspective. I'm not a power user in the sense that I use it to write documents, but at work we generate docx files from code (not a good idea) and a significant amount of the time we have perfectly fine files that render as we expect on LibreOffice but break unexpectedly on Word. Sometimes it even renders fine on the web version, but still incorrectly in Word itself.

Edit: I should clarify that I don't mean to contradict you. Just thought it would be an interesting perspective to read about.

Personally I deal with word templates and decades old xlsx files. OG office is my only go to and honestly it’s great. I don’t buy office for home so for kids projects it’s great. But not for payday stuff.
