Actually it goes even farther than that. Great optics on a high velocity gun in a strong frontally armored tank run in formations isn't of much use if the crew is inexperienced, the ground is broken and/or wooded, the opponent is experienced and lying in ambush. In such situations the "superior" Panther formation will die fast to side shots from M4's, m10s, m18s in prepared positions.
Exhibit one is the battle of Arracourt - 75 Mark IVs and 107 Mark Vs, 80 armored fighting vehicles such as assault guns vs the 4th Armored division (190 M4s and 77 Stuarts at full strenght), and a TD battalion (36 m18s at full strength). At the end of the battle 7th Pz. Army had 62 effective vehicles left tot he loss of 41 m4s and 7 Stuarts.
Studies showed that the winner in most tank engagements was the side that was able to set the nature of the battle (defensive lines, ambush, etc) and fight according to its strengths. This is not unlike airplane dogfighting where it is much less important how the planes match up then whether the pilots know how to use their plane's strengths and avoid its weaknesses.
There were many other advantages that the allies had that aren't sexy enough to qualify as "super weapons" and so don't get the attention of fanbois.
The US had industrial innovations and advantages not available or not used by the Germans. The US was at the forefront of rivet and flush-rivet technology, and TIG welding of aluminum, meaning they could build planes faster, stronger and lighter than the Germans. This isn't sexy, but it does make for the fast building of better planes.
1000% in agreement and I am glad you into depth for I am at work and didnt want to lol. But yes your right all those factors made up for the shortfalls of the Panther/Tiger/Ferdnand/JadgPanther/JagdPanzer. For many German machines the armor was great and gun was great but the equipment i.e. engines were not so hot nor were transmissions/ turret mantle's (Panther before model G I believe had a mantles that allowed Allied tanks to shoot it and the shell would ricochet into the hull and often kill the driver and take out the forward transmission). Then again look at the Allies with vertical stabilizers ( a concept many German tanks lacked). The winner of tank battles was nothing short than from the better men/tactics/and those whom had the stronger will to do what ever it took to win. There was no mythical machine that won everthing for either side.
