I know the flash would win so easily but I want to see if anyone can make a good argument

The Flash is faster than the speed of light, which is much faster than a nerve impulse. That means that the Flash can bitch-slap the orphan out of Batman before an electric impulse travels from Batman's brain to his muscles.
Technically Batman could die before realising he is in pain. Thats how fast the Flash is.1
