Maps are to be read. If you want a subway map to frame for your apartment, then the current/old one looks nice, but the new one is just easier to read - particularly in a moving subway car, through a dirty pane, and from 3 feet away. Especially in the age of smartphones, if you're doing navigation on a train (or station) you likely don't have a phone or are already lost, the map should be optimized to be easy to read in either scenario.
