It is already many years ago since that I started to do certain jobs in Libre Office (back then it was still OpenOffice.org) even if I had MS Office. I mean, it was better at certain tasks and costed nothing.

In all fairness, back them I also had to use MS Office for certain other tasks, but luckily I don't need that anymore.

Now there is Confluence instead however to mangle our docs and waste our time.
