Do you have any concrete examples that you're thinking of?

In particular, I found that having to include all the fields is kind of a PITA compared to AR. I also just find the mental model of an AR object to be really easy to think about in terms of the simple cases. Before save, after save, accessors, and just having methods available on the object all seem really intuitive compared to changesets. Not that I didn't figure those out in short order, they just seemed a bit clumsier. But I am not super deep into Ecto, either, so maybe I'm missing some places where it shines.
