There are indeed ramifications, the main one called "component sensitivity".
Component sensitivity refers to how component tolerances influence key filter parameters.
As an example: if a resistor value is off by 2%, how much does this influence cut-off frequency, gain or Q.
The Sallen-Key filter is pretty bad in this respect, the MFB filter is quite good.
With proper component selection, it is possible to keep the sensitivities below 1 for the MFB filter, Sallen-Key is always 1 or greater.
The figure indicates tolerance influences. With 1, a 2% resistor or capacitor tolerance will influence key filter parameters by 2%.
The maths are not simple, but online filters calculators like the one from TI handles this quite well.
