True, true - it's worth contrasting US and USSR production practices - the US had any number of Sherman variants but, through rigid manufacturing specifications, still had decent parts compatibility across the type, whereas the USSR, utterly focused on throughput above all else, simply shelved several improvements to the T-34 until they could fit them into the production line without interrupting the volume of tanks built.
There's also the point that the actions that made the British Firefly famous - the initial encounters with significant numbers of heavier tanks in France - the US had an equivalent tank, armed with the US 76mm - not quite as good at knocking holes in tank armour as the British 17pdr, for sure, but still more than capable of killing anything the Germans could put in front of it - but didn't bring it because the assessment was that they would not be necessary. ISTR they had 200 of the things parked up somewhere in the UK.
