G3 and N3 value depended on the battle context

How would the G3 and N3 designs fare against a South Dakota-class battleship?

The G3 suited a mobile fight, while the N3 became more attractive in a fleet action where armor and heavy firepower outweighed agility.

The G3 has an advantage in a fluid engagement because its speed lets it shape the fight. A South Dakota is preferred over an N3 in an isolated duel. In a fleet action the choice reverses because the N3's armor and heavy guns become more valuable. Formation speed and the need to support other ships reduce the maneuver advantage that would otherwise favor the American design.
