Diodes have quite big forward voltage, like 0.5V, depends on current but in any case it means lots of wasted energy. FETs got highly optimized over time, can be switched on with only minuscule resistance and also can be miniaturized.
Modern FETs are capable of switching spot welding currents without getting destroyed, while in thumbnail-sized package, imagine that. My grandpa was an electrical engineer and would be completely blown away by such a component.
