Tribal versus Fletcher destroyers

Which wins a fight between a Tribal-class and Fletcher-class destroyer?

Fletcher is favored in a torpedo exchange, but Tribal is favored in a gunfight; first effective contact decides the formation battle.

The result depends on how the engagement develops rather than a single overall ranking. Fletcher can launch a larger torpedo spread, though early American torpedo defects reduce the certainty of that advantage. Tribal's eight 4.7-inch guns provide greater destroyer-killing firepower once the fight closes. Because both navies preferred flotilla actions, detection, the first effective salvo, and how each formation evades torpedoes matter more than an isolated one-on-one duel.
