I don't think the comparison is quite apt, because while LibreOffice has no support for collaborative workflows (short of error-prone shared drives), QGIS can connect to quite a few geospatial databases, with third parties offering plugins for their own cloud platforms.
It would be nice to have better support for browser-based sharing and editing, but the desktop-based parts are there already.
