My suggestion is that: if you use the MS package properly, it works, and the cost is not too much -> continue this way. Easier, lowest friction option.
Otherwise LibreOffice or the other OpenSource alternatives work more than ok. But you might be introducing some (small) issues here and there, depending on the user's expertise, this has to be considered.
Good luck.
