Peckstar pretty much summed it up.

The only downside of being closer to the exit of pit lane is what we saw at Phillip Island and played out many times between SBR and HRT back in the Ambrose Skaife days.

If two enter pitlane nose to tail the car pitting closer to the exit risks being impeded by the car pitting closer to the entrance if the the pitstop times a roughly equal.

Why you may ask?

The car pitting closer to the exit may have to hesitate exiting his pit knowing that he risks impeding the car behind him. Entering the pit the cars can run nose to tail but exiting the pit the car closer to the exit cannot risk such a close margin by pulling in front of the second car.
