Why isn't Erich Hartmann talked about that much?

I notice a lot times, when people mention aces they say names of Americans, Canadians or British. Like I know he was on the other side, but no disrespect to these aces. They flew mustangs and spitfires. Erich was flying when Bf-109 was becoming older and not as fast and maneuverable as the allied planes. Also his fighting techs were different, and most of his kills they didn't even see him before it was too late. 352 kills proves he is most skilled ace of all time but yet.....he is not mention as much
