Yes but I must point out that it makes a lot more sense to be discussing the Soviet lend-lease Sherman as we've been seeing that in game as wrecks as well as elsewhere... Did the M4A2 have wet storage?
Safety is all well and good but can it destroy stuff as well? Cardboard suggested that the HE shell was more effective in the Sherman, does that imply that the AP performance for the 75mm was worse...?
The early model Shermans (1942) were superior to most early model p4s. But the Germans were already working on upgrades due to their experience in Russia, AND their upgrades could reach the battlefield faster from production. The US wouldn't yet know about the about-to-be obsolescence while the Germans were already working on better PIvs and on the PV. The US would improve the Sherman and design the m26, but anything the US did accomplish would also still be 2-3 months (at least) from delivery since they had to cross the Atlantic, get prepped in England, and then cross the still constrained supply lines across the Channel and through war-torn France.
The later Shermans had the higher velocity 76mm gun and the AP rounds for it were very effective. But they were in very short supply since most were allocated to the m18s.
