I feel like Dawson and, to a lesser degree, Tyson, go looking for high-fives for dunking on the dumbs, which doesn't do well at spreading an appreciation for science to those who need it.
Sagan and Feynman seemed to have a much humbler yet more effective way of helping people realize how amazing science can be if they'd just take some time to think about things and question what they believe they know.
All great minds in any case.
Happy Carl Sagan Day!
