I would definitely rank it higher if you consider everything that makes up Africa including the original village, theater area, this new marketplace, the safari and Pangani forest. In March, we spent nearly 3.5 hours in Africa between the lion king show, lunch at Tusker House, the safari and walking Pangani. It was then I realized how truly immersive the entire land is. It seems natural, but everything there was designed and built (or planted by design). Much larger and immersive than any other themed land imo.
The one thing I suppose Africa lacks is more authentic shopping. However, at least the main store in the village does offer some unique items not found in other stores in the park and are somewhat specific to the Africa section.
