Comparing British and American 14-inch guns

How did the King George V-class and Tennessee-class 14-inch guns compare?

The newer King George V-class guns were judged better, although the Tennessee-class weapons remained capable.

The 14-inch batteries of the British King George V class and the American Tennessee class receive a high-level comparison. The British weapons receive the advantage because they were newer and judged better. That assessment is immediately qualified by calling the Tennessee guns capable weapons that should not be ignored. No figures are supplied for shell weight, penetration, rate of fire, or fire control.
