Primarily these days I'm bouncing between Egyptology books and translations of original texts. I used to be a lot more dependent on the stuff that temples had already digested, but at the moment I'm doing a lot of my own research and interpretation.
I tend to trust that most recent peer-reviewed publications are reasonably sound, so I tend to prefer the ones that make the most emotional sense to me, for better or for worse, where that is relevant. (In cases of 'such and such festival was held in this manner and on this date' it's just a fact, and that's not something for which evaluation on emotional criteria is appropriate.)
I know of no contestations per se, though I am aware of some of the standard disagreements in the field.
