Not sure how often two ace pilots met in combat and sometimes when they did, it wasn't quite like in the movies. There were legendary one on one fights, like Cunningham vs some shiite hot MiG-17 driver. Sometimes, when two quality pilots met, they did go at it. One fight that comes to mind was Saburo Sakai vs VF-5's James "Pug" Southerland in an F4F on 7 Aug 42. Though it was Pug's first fight, he was a highly experienced aviator and had just scored the first kill of Guadalcanal, downing a Betty bomber. Sakai had destroyed or damaged 50 allied aircraft and only jumped Southerland when he was getting the best of Sakai's two wingman though Southerland was out of ammo. Pug's F4F was found a few years back, in the jungle and he still had some ammo in its wing. His Colt 1911 .45 was found too!!! Crazy in that in his book, Sakai had said he had hit the Wildcat's prop and when the wreckage was found, two 7.7mm holes were found in the Wildats prop. Anyway...
