Maybe an example will help.
Let's say we are recording from the center of a meadow surrounded by trees and 
it is dawn on a spring morning and we are interested in a particular sound we 
can faintly hear in the distance. We us identical high quality recorders to 
make simultaneous recordings with these three arrays: Jecklin disc stereo using 
two omnidirectional Sennheiser MKH8020's with self-noise of 10dB; narrow angled 
stereo using two cardioid Rode NT1A's with self-noise of 5dB; and a single 
super-cardioid Rode NTG1 with self-noise of 18dB.  Which recording will resolve 
the distant caller best? Which one the worst? And why?

I'm sure people can come up with a variety of answers.

David, I know from what you say that you believe the super-cardiod will rank 
best. But I think that the higher-self noise could bury the clarity of the 
sound.
