Denis,

The benefit to using an external resistor with the bypass circuit wired correctly is that when the starter is engaged the balast resistor is bypassed putting the full battery voltage to the coil for a better start.

If you use an internal resistor coil you loose that feature and the already low voltage while cranking the engine over is made even lower causing hard starts.
