With a break-before-make power mux, there will be a period of time (tSW, switchover time) where the input supply is not providing power to the output. This will cause the output voltage to decay based on the following equations:
Therefore a faster switchover time, tSW will result in a smaller voltage dip on the output, VDIP.
