Comparing carrier air wings for a war delayed to 1942

Which navy would have the weakest carrier air wing if the Second World War began in 1942?

None is clearly worst; the outcome depends on how delayed war changes development and on how each mixed air group is employed.

The comparison weighs fighter durability and speed against strike-aircraft development rather than ranking national air groups by one type. Wildcats and Dauntlesses remain capable even if the Devastator is a weakness, while Zeroes, Vals, and Kates bring a different balance of speed and striking power. Britain might field a developed Barracuda and a Skua-replacement dive bomber rather than the historical Firefly because radar and beacon development could alter the need for a long-range reconnaissance fighter. A Gull-wing Seafire could be dangerous to the Zero, but the Wildcat's durability also matters. The answer therefore resists a simple national ranking: the delayed war changes the development path, and employment determines which mixed air group performs best.
