Yep, most countries during WW2 that had enough industry to produce tanks figured out a fairly decent medium tank that you could churn out quickly and cheaply was better than a handful of really expensive good on paper heavy tanks except the Nazis. The Sherman and Cromwell for example. Meanwhile the one chance Germany had of making an actually practical tank after the panzer IV was the panther, but Hitler was such an incompetent micromanager he insisted on giving it enough armour to rival heavy tanks, nullifying the mobility benefits of a medium, making the transmission constantly break, and causing the price and production time to increase.
