Turbo-electric drive versus geared steam turbines

What are the practical differences between turbo-electric drive and reduction-geared steam turbines across warship sizes?

Geared turbines were lighter, while turbo-electric drive traded machinery weight and conversion losses for rapid shaft control, flexible power distribution, and survivability.

A geared turbine plant was lighter, while turbo-electric drive added generators, motors, copper windings, and extra energy conversions. Early electrical systems also raised reliability and damage-control concerns. The benefit was greater control over shaft speed, including rapid reversing. With suitable electrical connections, surviving generating machinery could power multiple shafts, preserving manoeuvring options after damage. Turbines could also run nearer their efficient operating point without matching propeller speed. Treaty weight limits made the machinery penalty harder to accept even where those operational advantages appealed.
