Which is your favorite Sims 2 neighborhood or sub-neighborhood?

Belladonna Cove! I love the apartments and the different districts, and I find the families interesting as well. The intro cinematic with that big statue of Bella is also one of my favorite hood cinematics.
Desiderata Valley comes in second, although I'm slightly biased since it's the second hood I ever played after Pleasantview and I had really fun times with my custom family there. It's a nice quiet suburban town and I find it better for normal gameplay with custom Sims than the dramatic soap opera with all its captivating characters that is Pleasantview.
