Knowing a vet personally for some 28 years it would be the Panzerfaust over the Panzerschreck. the heavier weapon was ideal and destroyed many a Stalin/T-34 but it was the smaller close in Panzerfaust produced in many numbers that bolstered the moral of the Landser especially on the Ost frontin 45. As my friend Helmuth told me repeatedly that a Panzerfuast was better in the hands than a karabiner.
