I get your "different personalities for different roles" point, and it's a good one. But you lost me on the "niceness can't compete" argument. Why not? And to me, tough isn't the opposite of nice. Being nice doesn't mean being a pushover. It means being courteous and professional. I'm not sure what you're implying when you say niceness has limits. Are you saying being ethical is not competitive? Because I would strongly disagree with that.
