My org uses Google Docs as office suite and I find it quite good and prefer it over any flavour of Microsoft Office. Nevertheless, there's a _huge_ and vocal push against Google Docs suite in favour of Microsoft Office from some internal stakeholders. None of the complaints from this group go beyond something to the tune of "I know Excel better".
As good as LibreOffice may be (I personally think it is _not_ better than Google docs) and as much as I like the romantic idea of open source office suite, I don't believe this will be successful/sustainable in the long run. The bulk of office suite users are not interested on using alternatives. These users want office running on their machine, period. I'd even venture to say that most users would rather have apps installed instead of Microsoft Office Online.
