The Flash is faster, which is why he's called the fastest man alive. Impulse stated that Superman can reach 99% the speed of light. Wally West (Flash) can hit the speed of light and even beyond. The Flash has the Speed Force, that's what gives him his speed.
I know flash is faster by far, he is the fastest, he turns into pure eneregy when he gets going faster than light, but at that speed he cannot do anything..ie...rescure people, block bullets with his body and do everything else superman can do.
