Why Saipan and British light fleet carriers are difficult to compare

Why did the United States complete the Saipan class, and were British light fleet carriers better ships?

Saipan offered fresh postwar flight decks, but British light fleet carriers were larger purpose-built aviation ships, so the shared label hides a major capability difference.

The United States completed the two Saipan-class ships because they provided new, efficient flight decks while older wartime light and escort carriers moved into reserve. British light fleet carriers were purpose-built from the large HMS Unicorn aviation-support concept, while Independence and Saipan grew from cruiser hulls. The labels overlap, but the resulting ships differed sharply in hangar volume, aircraft capacity, endurance, and intended use. Carrier categories make more sense when compared by design origin and capability rather than by the abbreviated class label alone.
