Churchill and Sandwich swap First Lord eras

How would Winston Churchill and Lord Sandwich perform if they swapped eras as First Lord of the Admiralty?

Churchill would probably cope but be constrained by the older system; Sandwich's strong administrative instincts could make him highly effective with modern tools.

In this counterfactual, Churchill would probably manage in Sandwich's era because the established Admiralty system would limit how much he could change. The imagined clash with St Vincent is a joke about personalities within that system. Sandwich's strength is his administrative ability, compared here with Pepys's, and the expectation is that he would welcome the later era's technology. His approach also involves keeping political intrigue within the Admiralty under his own control. These are judgements about how the two men's habits would translate across periods, without predicting particular wartime decisions.
