Who is stronger megalodon or killer whale?

I know that a megalodon is stronger. A megalodon was an extinct species of shark, and it was even bigger than a great white. A man that was five to six feet tall could step through its jaws without touching the mandila. A blue whale can be dangerous, but it is a slow-moving animal and does not have many defense mechanisms, but being hit with its tale could be fatal, though very unlikely.
