I'm about 2 years late for this thread, but even in light of Luke Cages strength and feats, Luke Cage goes down hard.
#1: Captain Wonder is physically superior to Luke Cage
#2: Captain Wonder is mentally superior, seeing as he made a chemical that gave him incredible physical qualities that would make Erstine wet himself. Albeit, it was actually accidental, even with that aside, Captain Wonder was a professor.
#3: Flight and Speed advantage. Theres really nothing Luke could do here that Captain Wonder wouldn't do better.
