All incarnations of the Flash can move, think, react at superhuman speeds. Some, notably later versions, can vibrate so fast that they can walk through walls, travel through time and can also lend and borrow speed. Furthermore, all members have an invisible aura around their bodies that prevents themselves and their clothes from being affected by air friction as they move at high speed.
Which means The Flash > every other super hero.
Bonus fun fact: It is understood that Flash wears no underwear as it is impractical and uncomfortable at high speeds.
