I think there are 2 components to look at articles and comments.
I don't know if it is nostalgia, but I recall preferring /.'s articles from 15ish years ago (compared to what /. and HN have today). Maybe that is a reflection of the news at the time, my age, the communities' interests, or a combination of the above.
With HN, I wish I could filter Valley specific news ("Zucktown, USA"[0] would be a recent example). HN aims for news for both Jobs and Woz types, where I think /. was really focused on just "News for Nerds, stuff that matters." That's all I really wanted.
So in terms of articles, I don't know what to believe. But I know that HN's community is more civil than /.'s, and this is one of the few sites on the web where I read the comment section.
