Oh of course HN has a ton of problems and problematic solutions (greying out people outside of group think - shouldn't it be the opposite?) but it's way better than FB. Paradoxically, I don't remember when I used HN main page, I'm using alternative interfaces displaying censored posts etc. - one of the many things you can't do with FB.
Of course HN is better than Facebook. It's moderated, limited in discussion topics and the user base skews heavily towards higher educated, older professional types.
It's like being at a professional work event and truly shocked that everyone is well behaved.
