Noise is just a weighted probability distribution of voltage over
time. Two different sources will have the same distribution over a
period of time, but not the same at any given moment of time. So, they
mix differently and more powerfully than just adding a single signal
with itself - turning up the volume so to speak.

Polyphonic patches, for one.

Yes. But when that's exactly what I want to do (obtain multiple random
values on the same clock edge, nothing else will do. Multiple S&H
modules sampling the same noise source will give me all the same
values, or values very close to each other given component variations.
I have white/pink noise in my MOTM 100, digital clocked noise in my
Dark Star, and shift register clocked noise/white noise in my Noise
Ring. I find them all to be useful, and use them quite often in the
same patch.
Your mileage and needs may vary, of course.
