Woah, there. That’s way, way oversimplifying things.
This is a the predominant view of the armor battle of the western front, but it’s based in large part on misperceptions and Wermacht Penis Envy. For some reason, everyone loves to believe that the germans were the finest warriors, man per man, ever - and that every vehicle they produced was a flawless feat of superior engineering, and only the raw masses of allies stopped them.
First off, the king tiger was actually the panzer VIb - which is kind of a fluke in the german naming scheme. When you refer to a panzer VI, it’s assumed you’d be refering to a tiger.
The tiger was, by far, one of the least seen vehicles in ww2. Due to Wermacht Penis Envy ™, we tend to think Germans used predominantly big ass, heavy tank killing monsters. In reality, the mediocre-at-best panzer 4s, the capable stug III, and assorted tank destroyers (marder 3s, etc.) were the bulk of the german armor force. Later, the panther (PzV) became more common, and it was - the later versions - quite an excellent tank - but not an unstoppable hulk.
The armor doctrines of the respective countries were completely different by that phase of the war. The US primarily designed exploitation tanks - and the Sherman, for a 1942-designed tank, was excellent, if not exceptional, in that role. If you compare it to it’s contemporaries, it’s fantastic. Good, well shaped armor, excellent reliability, good mobility, and a capable gun (with a good HE shell).
People with a casual knowledge of the war tend to romanticize battles into the idea that rare german heavy tanks commonly battled ‘inferior’ masses of Shermans, which wasn’t the case at all. Tanks fighting tanks was a relatively uncommon thing in world war 2. Tanks were used primarily as assault weapons - and so it was typical for only one side to have them in any given armor battle. The tank’s worst enemy was the anti-tank gun - which the sherman, with it’s decent armor, and good HE launching gun was capable of handling - and the tanks primary purpose was to be a hammer to smash through enemy infantry positions with and exploit - not to fight other tanks. With that in mind, with it’s good speed, good anti-infantry gun, fair armor, and great reliability - it served a far more useful role in allied doctrine than any tiger ever would. Because they were at a disadvantage when fighting german heavy tanks specifically designed to destroy them is no reason to condemn them wholesale. One must look at the purpose and use of the tank - and given that, the sherman was an excellent tank for what it did, and doesn’t deserve the bad reputation it gets among people with a casual knowledge of ww2.
