Choosing capital-ship guns after the treaty system breaks

Would Britain choose 16-inch guns for prestige in the Defence counterfactual?

That is one preference, while 14-inch commonality offers a logistical reason to choose otherwise.

With treaty constraints removed by the Defence substitution, the KGV design is imagined with either more 14-inch weapons or a heavier battery of 16-inch guns. A participant asks whether prestige would favor the larger caliber. Alex distinguishes his personal inclination toward larger guns from the choice a historical planner such as Henderson might make. The competing 14-inch argument is common ammunition logistics with the new cruiser fleet.
