Combination of PLL PREDIV and MUL factors when some frequency is desired

Hi.

I have to reduce system clock from 72 MHz to 48 MHz. Input frequency is 16 MHz from external oscillator. I could achieve 48 MHz in two ways:

1. With PLL PREDIV = 2 and PLL MUL = 6 or
2. with PLL PREDIV = 1 and PLL MUL = 3

Is any combination better than other and why? Or the combination of those two parameters is not crucial, as long as desired frequency is achieved?

Thanks
