I'm fairly sure you're aware that there were more allied tanks than the M3. Etc. Except that it's far from a fact. If by "we" you mean the US then I'd ask you stop being so parochial. There were more countries involved than just you. How would you rate the T-34, or the KV-1 for example? At the start of WWII the French had better tanks and more of them. (To give one counter example).
