Neither one of them is really more powerful, power just comes easier to the Sith because they are more willing to take it. They are willing to kill hundreds for training purposes they are willing to slaughter entire villages for knowledge where as Jedi would not do so. So Sith are able to get power faster, however in the end neither one of them is really more powerful. And like Ush said the Dark Side will destroy itself sooner or later.
Hell, Ragnos may have been a demi-god, but he still died. Sadow could blow up stars, but he's dead too. Kun and Revan did what they did, and the Light got them eventually. Palpatine was stabbed in the back by his own Dark Side tutelage, who in turn was redeemed.
Fact 'o the matter is, all these baddies were the most powerful Force-users of their time, not just that, but Dark Siders as well. In the end though, all of 'em except Ragnos were defeated by the Light, despite their Raw Power advantage. Jedi, in the long run, pwnd the Sith.
offencivly the darkside has an edge over the light, but that doesnt mean they have more overall power. id say their fairly equal, just different. the darkside has the major weakness though. while it does seem to increase combat abilitiy it looks like it weakens self control and the ability to sense other things when your engaged in a fight becuase your so filled with anger and hate and single mindedly trying to destroy your opponant. so i think their around the same, just different stats in different places.
The Sith keep losing, yeah, but there's only two at once. Saying that, if there were more they would turn on one another ALL the time intead of just on weekends.
If the Sith could develop a structure of hierarchy that catered for more at once (and worked) then the jedi would be nothing more than a distant memory for fanboyz.
