it did create some probs for the panzer arm according to many panzer troop memoirs. they were useful and could be made in huge #s. the Sherman had some easy to set on fire problems. the tiger was lethal but too heavy for a lot of locations. panther had bad transmission. jap tanks were tinker toys when fighting Russians in '45. pnz 1 & 2 somewhat same. seems Italian tanks were usable but but not many produced. don't recall comments on JS series or Brit tanks. i'm sure they weren't trouble free. doubt any weapon system tool is perfect,can't think of any that were/are.
Panzer1 was never meant to fight, panzer 2 was a reconnaissance tank, panzer 3 was good but had little development options, panzer 4 was good, Panther had issues that were mainly slave labour and alloy shortage related than bad design, tiger had better soft ground performance than a lot of tanks, anywhere a normal person could stand on one foot would be safe to drive. King tiger was pushing the limit of a lot of aspects in terms of overall weight but ground pressure was good, we have German reports of King Tigers recovering panzer 4s and subsequently traversing the terrain where they were stuck.
T-34 76 was a little under gunned plus a 2 man turret, soviets knew about the issues but weren't planning on getting into a war with the Germans so soon, T-34 85 was more in the L48 class of guns than the long 75s or kwk 88 but still a decent tank. IS-2 uses 2 piece ammunition of large enough size that any sort of hit was bad, no real novel aspects just a big slow firing gun. IS-2 was relative specialist piece of equipment and was used as such.
M4 was an ok tank for 1942, pity time moved forward. M24 was a needed upgrade to the M3/5, M26 was in no way clearly better than the Tiger 1 that came out three years before.
Cromwell, good tank that finally had an overly powerful engine in the form of the Rolls-Royce Meteor, allowed the British to almost double the frontal armour without the need to even remove the engine limiter. Comet was decent with it's bastardised 77mm gun that could actually fire APDS accurately. Churchill ended the with 150mm frontal armour and was a very survivalable, made for infantry support which it did well, somewhat slow but the rate of the allied advance never outstripped it's unimpressive pace, by most accounts it had phenomenal cross country and hill climbing abilities and was the first tank that could neutral turn.
No notable Japanese tanks, apart from the Type 95 that gave M4s way more trouble on Tarawa than they had any right to. Italians could only make armour plate for tanks in small sections despite making effective warships, hence their blocky, riveted nature.
