I can see the advantages of both styles. Scale and proximity are very important to people traveling to destinations they don't usually travel to (often tourists), but the schematic nature of this new map definitely makes it easier to tell how the system interconnects.
It would be great if, in addition to providing realtime bus and train info, the MTA provided realtime station info so third parties could create maps in any style that were guaranteed to be correct because they would pull from live station data.
For purposes of a subway trip in Manhatten, for example, scale isn't that important - a train will quickly take you a long way if you can get on the right one.
