I agree with everything except you focused on corporate brands and there are many product brands more powerful and memorable than the corporate one.

Barbie is by far one of the strongest brands there is and Mattel pales in comparison.

Corvette is a much stronger brand than Chevrolette.

Star Wars is stronger than Steven Spielberg

The Harvard Business School is stronger than Harvard University.

The NY Giants football is stronger than the NFL

Etc etc etc.
