My interests lie in both Eastern and Western Fronts and i know all about Op Bagration but appreciate that it wasn't the sort of thing that was generaly taught or known about in the West, The Eastern Front was the main front that in the end that decided the war and Bagration was one of the greatest breakthroughs and advances in History, but Normandy was not easy going at all !!!! If you think it was easy have a look at photos of the Falaise pocket.
It was three months of hard slog that cost hundreds of thousands of casualties on both sides and the second front took some of the pressure off the Russian forces, Stalin had been wanting a second front since 1942.
Also Some of the German units in Normandy were poor quality second rate units but i don't think you label any of the following with that , LAH , Das Reich, Frundsburg , Hohenstaufen , Hitler Jugend , Gotz von Berlichen , 2 Panzer , 9 Panzer, 21 Panzer , Panzer Lehr etc etc.
Some of the best German units who didn't make Normandy easy,
