Using many FETs decreases the on resistance for better efficiency. A single large FET may not have ideal resistance, switching speed, etc as many smaller ones placed in parallel. And, FET gates are voltage driven (very little current). I like to think of FETs like a garden hose where the input and output is the hose and the gate is a set of fingers squeezing it to limit/stop current.
