It depends on how you define "powerful" and which particular cartridges you are comparing. Most people define power as some combination of velocity and muzzle energy, and different cartridges have different specifications, so one particular 9mm may be more powerful than one particular .40, but another 9mm may be less powerful than that same .40.
