Shining || Responsive?

Google recently previews its new Google Maps. The new interface looks more comprehensive and stunning:

However, the trade-offs are speed and memory comsumption.
 
At the time of writing this post, I still favor the classic Google Map which offers a much simpler UI but more responsive experience.

New Google Map 

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
iexplore.exe                  1804 Console                    1    461,972 K 
firefox.exe                   4800 Console                    1    645,508 K

Classic Google Map

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
iexplore.exe                  4148 Console                    1    160,116 K
firefox.exe                   1204 Console                    1    221,092 K

Software design needs to strike a balance between performance and functionality and UI in order to provide great user experience for customers. So,

1. Do you really prefer the Shining map to the Responsive one, when you are running out of time for catching a flight, but only eager to know the fastest route to the airport?
2. User-oriented is good, but not glod-plating
