Why available Panzer IVs could matter more than superior Panthers

Was Germany better served by pursuing the Panther or by improving the Panzer IV?

Improving and mass-producing a maintainable Panzer IV could yield far more usable combat power than a technically superior but scarce and unreliable Panther force.

The Panther was an impressive technological concept, but Germany invested too much in a complicated new design. An improved Panzer IV with better armor, simpler production, and easier maintenance could have provided more usable strength. The numerical example separates paper quality from combat availability: ten exceptional tanks at thirty-percent serviceability produce only three ready vehicles. A rival able to manufacture five simpler tanks for each one and keep most of them running can bring roughly thirty vehicles to the same fight. The superior tank must then win every encounter, while the mass force needs only occasional successes to erode an irreplaceable advantage. A later follow-up widens the criticism to German industrial management and its repeated pursuit of high-technology designs over practical output.
