Both work, but I think the range elevators simply have no exits for the unsupported floors and can go high speed to the first supported elevator. They probably do have exits though, in case another elevator breaks down.

Taller buildings will require you to transfer to a different elevator once you've reached a certain floor; one because else you get cables that are hundreds of meters long (with the weight to match), and two because else you'll need more elevators and -shafts to service all hundred+ floors in a timely fashion, which takes up real estate / floor space.
