Comparisons between the Allison V-1710 and the Rolls-Royce Merlin engine “families” are inevitable. What can be said for the Allison; is that it made more power at less boost, with a longer time between overhauls, and with a parts-count that was nearly half that of the Merlin engine; which greatly facilitated mass production.
Why did Allison add a supercharger to the V-1710?
