Value: "The Fall of Blackbottom" vs "The Delian Tomb"

Question for those who have both: The Delian Tomb provided INCREDIBLE value for the price. How does the Fall of Blackbottom compare?

Obviously, I don't expect it to exactly match it. The Tomb is such a phenomenal adventure that it makes the perfect on ramp for the system. It's the door crasher that gets people in the store, so to speak. But is Blackbottom at least solid bang for your buck?
