With the highest kill-to-loss ratio among all the tank destroyers the United States deployed in World War II, the Hellcat was the most efficient. M18s were excellent in direct fire support, other improvised duties, and fighting. Even though the Hellcat was deactivated a while ago, its legacy lives on.
