All the changes in Google over the last few years (Penguin, Panda, Hummingbird) emphasize content and authority, so the trade publication is defnitely a better link. It's not about Moz rank - the highest ranking pages on Moz are irrelevant to my target audience.
I would think the priority should take into account follow vs. no follow links, authority, and content type. It should also see which links are more correlated with our list of keywords.
