Heathen question

[hearthstone]

So what do you consider the difference between the lore in the Eddas and the lore found elsewhere (I have specifically the sagas in mind), in terms of how much weight you give to particular tales? I'm thinking that I've always considered the Eddas to be more...well, "trustworthy" isn't really the word because I think you always need to be looking carefully at these texts, but I can't think of a better one. But I know that that may be my own bias in favor of texts having more to do with tales of the gods.

In particular I'm thinking of Gautrek's saga, the part where Thor and Odin take turns establishing Starkad's future (Odin giving him good things, Thor giving bad ones), and also including that wonderful bit about the "symbolic" sacrifice to Odin (heh!).
