Pepper has an arguably stronger down tilt due to its sheer combo potential, though it does require a lot more skill and precision to utilize fully. The main uses of it are to a) combo into side air, which spikes and leads into another down tilt, and so on, and b) to combo very easily into neutral air, which, as you mentioned is very good, especially when killling at the ledge.
