Our take
The default desktop office suite for anyone who wants their documents to stay local files on their own disk, no cloud, no account, no telemetry. The honest trade is the interface feels dated next to commercial suites and the cloud collaboration story is weak, so live co-editing is not its strength. Pick it for offline, private, full-featured document work; look elsewhere if real-time collaboration is the point.
