Superman flies faster than light speed, but can't fight at it
Flash is limited by time most of the time and even if he stops it or transports Goku anywhere Goku can literally break dimensions to escape them. Also he can move free of time without anything being able to stop him. And One Punch is a human barely on Krillin's level

One punch is slower and weaker
Superman is slower and weaker
The Flash is slower and hardly has any strength
