Hmmm... Well technically the dark side would Win. Basically the force can do just about anything, whether your light of dark, you just have to try it. An example would be that if yoda wanted to do lightning, he sure as hell could. The light side just doesn't do any of those abilities because their seen as evil. So all in all, light has this window of force abilities they can use, where as dark can use anything that they feel will get the job done. Including lightning to the face^^ The only way light has won so far is because the light side found out how to deflect lightning with lightsabers, oh no!
