Of non-262s, I'm betting that the Pony has collected more 262s than any other fighter (probably a lot died to bomber guns too). The typical scenario is a 262 jocky who got low and slow, and a Pony with a lot of altitude shows up on the scene and can pick up more speed diving on the 262 than the 262 has, or can quickly get, and the 262 gets pwned. I'm familiar with this scenario, from both sides. Arg.
Speaking of which, a few weeks ago I was in a Yak 9T and looked down to see a 262 several thousand feet below me, fairly low and fairly slow. I dove down got on his six, and he was starting to get away from me speedwise when I put a 37mm tater into him from around 700 yards out.
