With so many types of links, there are a certain type of links that would be a little much better when compared to the rest of the lot. Like what was mentioned previously, the contextual links would be the best type of links, and if those links are placed on a high quality site, with good metrics and good user engagement, then that link would be a big bonus to your site as the good link juice would flow to your site.
Then when you tier those contextual links further with similar quality contextual links, the effect can gradually be magnified in the process.
