HN certainly has a lot more startup and non-programming content than reddit. In my experience there is also a better balance between "early adopters" and "grumpy enterprise devs" (proggit in particular tends to be dominated by the latter, e.g. a lot of cynicism towards Node.js). I would like to say HN is simply generally more sophisticated, but some of my highest-voted comments on HR are sarcastic remarks (criticising the US seems to equal free karma).
