ADAU1452 clock generators - How to choose N and M

I'm using a 12.000 MHz oscillator input to ADAU1452 XTALIN/MCLK, and need to operate at 32.000 kSamples/second. With Divider at 4 so Input to PLL is 3.000 MHz, and Feedback Divider at 96, so System Clock is 288.000 MHz, I can use the combinations of N and M shown below to get exactly 32.000 kHz Base Output Frequency (using Clock Generator 3 which has 16-bit registers for N and M).

My question is, does it matter which N-M pair I actually use? For example, is the PLL more stable with some combinations rather than others? Any other considerations?

Thanks!

For MCLK = 12.000 MHz, Divider = 4, Feedback Divider = 96 for Base Output Frequency of 32.000 kHz from Clock Generator 3…

Does it matter which N-M pair I use?
