I haven't looked to much into the subject, but it seems to me the superiority of the German tanks came primarily from their way of using them and not so much from the superior quality of the tanks themselves. At the beginning of the war, the French, Poles, and British all had tanks that were not too bad compared to the Germans' but they were only using them for infantry support.
I could write a long response but I don't want to clog up the TV Show thread with too much tank talk...
...but that is absolutely correct. A large part of German tank superiority comes from the fact that to most Americans, the war started on June 6th 1944 when Tom Hanks hit the beaches and was pretty much over after he killed the only remaining Tiger tank with his .45. In this period, the German tanks were in fact superior to pretty much every one else...so long as you discount the Russian front since that ended with the bizarre sex scene in Enemy at the Gates. (In the same period - June - August 1944 the US, Brits, and Canadians were getting off the Normandy peninsula whereas the Russians had destroyed Army Group Center and had pushed deep into Poland.) Otherwise, from 1939-1940 the French and British had superior tanks to the Germans, on the main, but they were poorly handled and piecemealed out.
I meant to comment on this before, but was too busy and got reminded of your post thinking about your pop's way with words.
Dude, I could totally see you writing some insane novelized WWII text. Working in scenes from various WWII flicks and stuff. A historical, satirical, WWII movie fan-fict opus. It could be pretty awesome.
You know, I had one once. It was longer than the first two dozen Harry Plopper novels combined but then I feared that no-one would get the Tali-Ihantala/Skyrim panzerfaust to the chest reference and cried myself to sleep before throwing it away.
It ended like this:
Tom Hanks: Where's my Matt Damon!
James Colburn: You are my Matt Damon, Captain Hanks.
TH: Fine I accept. I'll show you how an American drama actor can fight.
JC: And I'll show you where the Iron Crosses grow.
