To make a long story short, the results were that the Germans were the most accurate, the Americans next, then the British, Japanese then the Russians. He commented specifically about Saburo Sakai and his supposed 61 kills. He basically said no one who has checked really believes that.
He also commented that he didn't think any of them were purposely lying only doing a sloppy job of verification with one exception. The Russian claims had no relationship at all to reality. He said they were basically just made up.
I suspect the same would be true of their sniper claims
So we'll forget about Lyudmila, justified or not, and use Matthias Hetzenauer(345) or Heinz Thorvald (300). Perhaps Sepp Allerberger(257),Gefreiter Meyer(180) or Oleh Dir (120). All good German snipers. Scores weren't my point. All snipers dealt with environment. Each, if he lived , used it to his advantage. As good as Hatcock was in hs environment the others , German in the case of WW2 , were as good in theirs. They lived. Would Hatcock have survived on the fields of Flanders or the rubble of Stalingrad ? Or our good Germans the jungles of Asia? We'll never know . There is no best.
