I should not even get into these sort of arguments, but thats BS. MG34/42 were pretty much without parallel in their day and have set the conceptual standard for GPMGs. This applies both from a production/enduser standpoint.
+1.
The freakin' thing still exists today virtually unchanged in the MG3. Even the famous American M60 incorporated many design elements from the MG42 (and FG42).
The MG34 was already the best general purpose machine-gun of it's day, the MG42 was basically a lighter, simpler and therefore cheaper to produce improvement on that design. Nothing anyone else had was even comparable.
