New York and Constanta.
New York is more crowded than Constanta, and, it has much more people than Constanta.
New York has many more buildings than Constanta, it has 4 really tall buildings like one of them named Freedom Tower. But Constanta doesn't have that many tall buildings. New York is 789 km² but Constanta is only 124,9 km², meaning that New York is much more bigger than Constanta.
