It's an interesting comparison, and Munich's rise is undeniable (in economic and cultural terms even more so than in demographic terms) but your graphs and figures only show us which urban areas are more populous within a specific, randomly defined area, regardless whether that area is reflective of their true expanse. They don't tell us much about the overall size of those cities. Hamburg is one of the least dense urban areas in Europe, that doesn't mean it's a smaller city than Munich (not yet at least). The Ruhr Area is larger than either, even if it has a smaller number of people in its 755 sqkm.
