Total hogwash.
That actually applies to your description of the Sherman.
The Sherman's chassis was based on the Lee/Grand Chassis a tank that had an obsolete design. That of an infantry support tank with a high silhouette to be able to carry its main gun in offset sponson like they did in WWI.
The reliability of the Panther had nothing to do with the Tank itself but with the fact that German factories where being bombed, only low quality materiel was available, low quality fuel where used, the same Tanks and crews had to be used allot more due to being outnumbered.
That is why German crews got number of kills that no allied crew ever come close to.
Actually Panther where produced even after the war and where used by the French.
When it come to reliability, easy production and generally cost efficiency the T-34
was far superior to Sherman.
If you think that a Sherman facing a Panther had a better chance of coming out victorious you are gravely mistaken.
