The main improvement HN has over Ars for me is simply threaded replies. It's been relatively old fashioned for a long time now, but it makes a huge difference for having actual conversations. Although I must say, the technical content on Ars has slipped a bit in the last few years. The science content is still OK though. Hopefully that's not just a reflection of my relative ignorance.
