Back in the day before Vampires, I had two main saves: one where I was filling out Newcrest and the other with my first family that I moved into the empty lot of Magnolia Promenade. In those limited world days, Magnolia Promenade felt especially personal and private so I liked using it for my main family. I didn't remove the retail lots, though. After Vampires Midnight Hollow became my favorite private world.
Just from my quick musings, I suspect Eco themed stuff could look good. While I like the idea of stuff that matches the Paranormal stuff pack for the scenery, with the retail lots it feels more urban. If you plan to keep retail, suburban style. If you don't, Paranormal SP style.
