ELI5:Psychologically and physically. What is the difference between water boarding and dunking someone's head in a bucket of water?

Before water boarding came into light. The more well known form of torture was dunking someone's head in water.
Is there something about water boarding that causes more physical or psychological trauma?

Waterboarding triggers all the fear and physiological reflexes of real drowning, but with the prisoner strapped down and water poured in a controlled manner, it is easier to administer and it does not carry the risk of actually drowning him.
