Sure the discussion quality is far better, if you're comparing to reddit in general. Discussion is often on par if you're on a niche subreddit focused on something technical.
From a personal perspective, the discussion quality on HN (on average) has declined over the past couple years. In the past the majority of comments were more substantial; it was more common to see paragraphs of well thought-out comments that delved into nitty gritty details when addressing a point.
But in the past couple years there's been a gradual increase in single-sentence comments that contribute nothing to discussion but only end up taking up screen space. Like the random person who wants to throw in their 2 cents, but have zero cents to offer.

Even HN is not immune to Eternal September.
