They faced mostly Tigers, Panthers, and fully upgraded/upgunned PzkwIVs. Note that the first two are heavy tanks, yet since the Sherman medium tank couldn't go toe-to-toe with them, the Sherman gets branded as "inadequate."
The Panther was a medium tank.
The M4A4 Sherman only had 51 mm frontal hull armor, and 76 mm frontal turret armor. The gun mantlet was also only 76 mm thick. This is more than the 1940-43 T-34-76, but less than the 1944 T-34-85.
In comparison the Tiger I had 100 mm frontal hull and turret armor, 80 mm side hull and turret armor and 110 mm gun mantlet. The Tiger’s armor was also of superior quality to all other tanks of the war. The KwK 36 L/56 gun should penetrate the Sherman’s best armor at well beyond 2000 yards.
The Panzer IV Ausf. H had 80 mm frontal hull armor and 50 mm frontal turret and gun mantlet armor. The 7.5 cm KwK 40 gun should penetrate the Sherman’s best armor at well beyond 1000 yards.
The T-34’s 76.2 mm F-34 gun using AP ammo should not penetrate the Sherman’s best armor except maybe at less than 100 yards. It should however penetrate the frontal hull armor at 500 yards. Using APCR ammo it should also penetrate the Turret at 500 yards and hull at 1000 yards.
The Sherman Firefly did not have upgraded armor, but did have a different gun mantlet which thickness varied between 38 mm and 89 mm.
