Who would win in battle LSSJ Broly or Super 17?

I bever seen GT. But I heard it was garbage and retarded. I say Super 17 because dude was strong but when it came to Cell he looked like a lil kid going against his own dad or something. And my true answer is Broly. Because in the movie they overpowered him and didn;t know what to do, so they gave it a stupid ending. Beat him by a punch from energy from the other Z fighters.
