Neither, that's up to your individual preference. Although I think that controversial threads have more noise, but sometimes provide a more enjoyable read.
The front page has an algorithm that is "less noise, more news" but if you go to the /active page, you get more conversation-driven submissions. I tend to load both up and refresh every few hours.
> The FAQ notes that submission rank is impacted by "software which downweights overheated discussions." A good rule of thumb for this effect is when the number of comments on a submission exceeds its score. Moderators can overrule the downranking for appropriate, not-actually-a-flame-war discussions.
