I'm not sure OP original question of Navy v. AF was answered,,,and I'm going to take a slightly different tack -
First, one can argue that "odds" of a flight billet are greater or less at the one service academy over another, and that real men fly off carriers, etc. but my BGO (long ago, in the time of hard copy Admissions catalogues and submitting the application in a paper package and then waiting months to here results without the feedback of online portals assuring us that everything was received ) told me to look beyond flying. Back then, statistically Flight billets went pretty deep into the class at Service Selection --if you performed reasonably well and
were physically qualified, you had a good chance to go aviation. The emphasis on
physically qualified is intentional, as that was usually the biggest limiting factor. Maybe less an issue now that Navy will get you Lasik after 2nd class year but many wanna be aviators didn't make that cut. And that is where the biggest advantage of USNA comes -- if you can't fly Navy, there are many more options for those that want to reach Command , ie. Surface, Subs, Marine Corps, and Special Warfare.
I am certainly not an expert on the AIr Force, but did spend 6 months at an Air Force Base (again, back when dinosaurs roamed the land) and it was pretty clear that if you didn't have pilot wings , you were kind of a second class citizen.
For OP -- DS should visit with an open mind. Air Force is what he knows, but there are some great opportunities at Navy. Who knows, he may like what he sees and set his own course. If not, well, serving in the Air Force is an honorable alternative to serving in the military
