The ADC is just new code to handle leaving the station. The docking part is exactly the same..... Unless you think they wrote brand new code (and reinvented the wheel) for docking with the ADC but left the original on the standard DC.
Although I don't like waiting over a minute in the queue to clear the station, it means I can check how dinner's going or read Galnet. If I want a fast exit, I'll just hit the throttle.
