Which battle in 1942-43 is considered the turning point on the Eastern Front?

The Battle of Stalingrad is widely considered the turning point on the Eastern Front in 1942–43. Fought from August 1942 to February 1943, it began as Germany’s drive to seize the strategically important city on the Volga and protect its advance toward the Caucasus oil fields.

The Soviet counteroffensive, Operation Uranus, began on November 19, 1942. Rather than attacking the strongest German positions inside the city, Soviet forces struck the weaker Romanian and Hungarian units guarding the flanks. They encircled Germany’s Sixth Army, which Hitler ordered to remain in Stalingrad despite worsening supply shortages and failed relief attempts.

The German surrender destroyed a major field army and forced the Axis to retreat from much of its southern advance. After Stalingrad, the Red Army increasingly held the strategic initiative, although the Battle of Kursk in July 1943 was another decisive Soviet victory. The Siege of Leningrad and Battle of Moscow were also crucial, but neither is the standard answer to this question.
