At best, Thorsson is someone to only carefully rummage through if you are already experienced in Heathenry. If you are a rookie, stay away from his material until you have a lot of knowledge under your belt to be able to effectively separate the wheat from the chaff. For every good academic quality article he writes or obscure book he translates, there's a book of his that is essentially a Satanic, Wiccan, New Age, Ceremonial Magick mishmash that will just confuse you and lead you down the wrong way.
I don't understand what you mean by the AFA favoring him. During the original split in which the Asatru Free Assembly broke down and split off into the Asatru Folk Assembly (Folkish) and The Troth (Universalist), Edred Thorsson was one of the main founders of The Troth.
The Troth, in particular, is pretty much the Patient Zero in the rise of Universalist Heathenry. Thus, with few exceptions (like some work that is put out by Kveldulf Gundarsson) it's literature, like "A Book of Troth" should either be combed through with a skeptic's eye, or outright avoided if you're a greenhorn in Heathenry.
I have not read Asatru: A Native European Spirituality yet, but as it is by Stephan McNallen, it ought to be good.
The fact that most of the negative reviews boil down to: "Racist!" "Loki Denier!" is a good sign:
