The Sport Propellers will allow for inverted flight while the 3D Propellers will allow for more advanced maneuvers while inverted. Like all performance upgrades there is a compromise to be made. Using the 3D Propellers with more advanced maneuvers will cause the battery to drain faster yielding shorter flying times with the stock battery.
