What was the most important naval contest of the war?

Was Pearl Harbor the most important naval battle of the Second World War?

Pearl Harbor was a turning point, but the Battle of the Atlantic was the essential campaign; Midway and the River Plate matter differently for American and British perspectives.

Pearl Harbor is treated as a decisive turning point and strike rather than a conventional naval battle because the American fleet barely participated in a reciprocal fight. The same distinction applies to Taranto. The Battle of the Atlantic was the indispensable campaign because North Africa, the Soviet supply route, Mediterranean invasions, and forces bound for Asia all depended on Atlantic movement. Midway stands out from the American perspective, while the River Plate announced early that the Royal Navy would fight globally.
