Only the Power. Some other people say that if you upgrade all at level 3 works better, but if you only customize the power, you'll see that the spread release many "magic bullets". It's like if you'll upgrade the Accuracy, or the Rate of Fire, take away some "critical chance" on the spread of the gun. Just cutomize that, and try it.
