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.
Flash states that Superman is moving at over 2000 miles/sec, which is also over 120,000 miles/minute, and also 7,200,000 mph. That's Mach 9350. I believe this is that fastest that I've seen Superman move under the Earth's atmosphere. He can, however, break light speed in the vacuum of outer space.
