Back when I worked a corporate job, we had to switch one large team away from Word because its conditional text feature regularly corrupted documents. Fixing corrupted Word documents was actually a line item in their budget, as I recall. (We moved to FrameMaker, I believe, because the team had used it earlier and thus needed little training to implement the switch.)
In general, back when I used Office, I found less popular features to be bug-ridden and unreliable, but perhaps we were just above the safe power user level. I've personally had fewer problems with LO. *shrug*
