Off the top of my head,
Pilot Service Kills
Erich Hartmann Luftwaffe 352
Gerhard Barkhorn Luftwaffe 301
Günther Rall Luftwaffe 275
Otto Kittel Luftwaffe 267
Walter Nowotny Luftwaffe 258
Wilhelm Batz Luftwaffe 237
Erich Rudorffer Luftwaffe 222
Heinz Bär Luftwaffe 220
Hermann Graf Luftwaffe 212
Heinrich Ehrler Luftwaffe 208
Hartmann flew the 109, Barkhorn flew the 109 and the 190, Rall flew the 109 and maybe the 190?, Kittel I think flew the 190, Nowotny flew the 190 and the 262, Batz comes to my memorry as 109 (not sure), never heard of Rudorffer, Baer flew the 109 and 262, Graf flew the 109, and I've never heard of Ehrler.
It's still very debated over the top ace for these two. Pokryshkin's squad would give a day's kills to a fallen squad mate so the extra money could be sent to his family. His unoffical score (as Soviet scoring only counted if they could find the wreckage) is actually 100+ kills, not to mention the ones he didn't count when he'd give the kills. Offical is Kozhedub, unoffical (and reality) is probably Pokryshkin.
I've read that
all Soviet squadrons do this. One way or another, Soviet kill claims were greatly exaggerated.
I've also seen Rechkalov placed over Pokryshkin.
From the Soviet list, I recognize Kozhedub, who flew Lavochkins, Rechkalov, who flew the P39, and Pokryshkin, who flew the MiG3, Yak1, and P39.
