I think German weapons are better, they were more technologically advanced. The Kar98 was the best bolt action rifle of the war beside the Lee Enfield. In my opinion the the mp-40 was better, I am not sure were you got the numbers on maximum range but it was 200m for both. The mp-40 was harder hitting and hard a larger caliber bullet, although the ppsh had a higher rate of fire.
