I found Higurashi and Umineko to have excellent character development, I personally prefer Umineko for its subtly complex side characters and intellectual story, although there are elements of this in Higurashi too. The plot does have a tendency to be confusing and the male leads of the series are both pretty irritating at first though.

Sadly, a good deal of the fleshing out of characters is left out of the anime adaptations and Studio DEEN's animation quality is appalling. Music is brilliant in both however.

Edit: holy shit this feels out of place after that last post
