Meanwhile LibreOffice is way better than the original MS Word in my opinion.
I don’t really use either Word or LibreOffice much as my needs are really simple, (I mostly get away with just plaintext tools).
What is it that separates these two for you?
Is it some specific missing features you rely on or something to do with UX?
It's a common problem with Open Source: who does the slog work of testing, tracking down, and fixing the simple bugs and perf issues? Evidently, LibreOffice doesn't have enough maintainer cycles to have good coverage of common setups. It's unfortunate and as a developer I feel for them, but as a user it makes paying Microsoft an easy choice.
