All the accounts I have read about for the German perspective give accounts of their great respect for the Western Allies artillery and fighter bombers (Jabos), the Soviet heavy tanks (T-34, KV's, and JS's), the Soviet sub-machine guns, the British Matilda tank and the French Renault and Souma Tanks, and various other individual types of weapons which they either subsequently used or tried to copy.
By most accounts however, the Germans had (or believed they had) the most superior type of equipment in every field. Their biggest problem was that they couldn't supply that equipment in the quantities that were required or, believing that they had the best, they didn't try to improve what they had until it was too late.
