Schematic Review: Led Driver request

Hello, I'm making a circuit on EasyEDA that includes 9 leds and they need to be controlled individually.

They also have to produce a very stable light, so I decided to use one driver CN5501 for each led (so 9 drivers in total)

In this way I'm sure a current of 350mA flows on the led even if I turn all the leds on or just only one.

The current of 350mA is regulated by the 0.4Ω resistor.

I use a mosfet SI2302 to turn on or off the led but I know that the driver also have an Enable Pin.

However, a doubt has arisen in my mind: is it better to use the mosfet to control the led (as I'm doing now) or should I use the Enable Pin available on the driver?

This is the circuit I made.

Edit: I change the circuit like this to controll the Enable Pin of the driver with a microcontroller.
