What I'm really fatigued of is the whole dick measuring contest caused by professional sports (lol.) and the scattershot nature of the literature- I find that people's conceptions based generally based around theorycrafting/biases (pro-allied or axis, their own biases or the authors) as people use the same sources they downloaded from the internet..there are entire forums of tank heads that are so narrowly focused on armor and generalized sources that it resembles autism to me.
The whole 'Duel' series is an attempt to profit off of this, and is rather patronizing.
Zaloga, for instance, has an rather attritionist (as opposed to, systematic) mindset in his thinking and this leads to many questionable conclusions. His chapters about the Eastern Front in his 'top tanks' are pretty bad and blatantly shows that he is not well read on the subject.
Certain things like war experience cannot be easy theorized- eventually one has to get down to reading EVERYTHING operational on the subject in order to get general opinion statements and even these are liable to change as new things are read. It actually defies the theories being tossed around by Osprey & co.. about kill ratios, operational readiness, and such.
Frankly, by way of NARA, its been available even a good deal earlier. If people had taken the time to actually read up on the Panzerlage, they would have seen that the Panther was not on average less (or more) reliable than either the Tiger or the PIV after the teething issues had been worked out.
In general, its quite astounding just how underused (or selectively used) even the completely open German archives still are even in Western historiography, not to mention just about everything that came out of the Soviet Union/Russia until not long ago.
Roughly speaking, the Panther was around 20-25% in 1.PzA, 4.PzA during the defeats in the Ukraine 1943/44. The Tiger Is in the two armies were not much better. PzIV were @ ~45% and Stug were @ 55%.
