Yeager is the most famous NOW because of what he did after the war not during the war. Yeager made his name with the X plane flights, not a string of WWII victory's.
Of the WWII era pilots Bong tops the list IMO, with Chenault, McGuire, Boyinton, & Gabreski right behind. Thats for US pilots, Sakai for the Japanese, Bader for the RAF.
Growing up I had no idea who the LW aces were, and didn't really care. Same for the Russian pilots. But the Bong/McGuire race to the top everyone knew about.
And even back then I'd heard of the top Japanese Ace Sakai. Once Black sheep hit the TV everyone knew about Pappy B & the Corsair drivers.
In some respects Chenault should get a lot more respect than he does.
He virtually wrote the book on how to defeat the Japanese fighters.
Would Pappy have done as well as he did without Chenault showing him how?
I don't know what happened to Chenault after the AVG disbanded. Nor how many kills he racked up with the AVG? And did he actually get a chance to fly after the AVG was disbanded? I think if he'd of been allowed to continue to fly combat for the rest of the war he'd of blown them all away.
