They both are equal in my opinion, they both are kind of balannced. One is your born good, but you have to maintain being so. The other you overcome the evil with a great effort, is also a good act. Because you finally gave up that negative choice.
I think to overcome your evil through great effort is really better. In this way, we know that this thing is wrong and we won't dare to do that again. However, to be born good is not too better. Because we would not know what good is and what bad is much better! Right? :)
