My point is that it's really the storytelling/gregarious nature character. There is no shortage of people who were at the Manhattan project and won Nobel prizes or were prominent. A partial list: Oppenheimer, Bethe, Rabi, Teller, von Neumann, Compton, Fermi, Segre, Ramsey, Alvarez. There are easily many more. Schwinger was at Rad lab.

Schwinger was considered a tremendous educator. I think he had ~90 PhD students and four won Nobel prizes. His lectures were often described as Mozart symphonies. I have studied parts of his books and the experience was always eye-opening. But, his education was focused on students, mostly graduate students. He was also a shy character.

In any case, I still love reading Feynman and Schwinger's works. I would also include Sommerfeld, Pauli, Landau, Weinberg in that list.

Sorry, my wording was imprecise; when I said "educator", I meant popular science educator, along the lines of Asimov, Sagan, Neil DeGrasse Tyson, etc. I can't think of anything Schwinger ever wrote or a public lecture that he gave that would be accessible to a general or even a semi-technical, non-physicist audience.

But, beyond that, yes, I think we're largely in agreement.
