If it has NAV, it is a SV or SL with a heat pump and remote access. If no NAV, it is a S with no heat pump or remote access.
The QC port is nice to have, but whether or not it is useful depends on where the car will live. I have a QC port on my SV, but have not used it once in almost three years. Now that I have a new battery, the need for it is even less, especially since I don't try to do long-distance travel in the Leaf.
It if has a backup camera, you will see it in the canopy right above the license plate. They are nice to have, but I do quite well without it. I find them a distraction, as people tend to focus on the screen and not pay proper attention to the mirrors and windows while backing up.
