John,
All important to me. :-)
What mic specs don't tell you is the frequency response off-axis whic
is often all over the place.

My final judgement is with my ears and known headphones. Polar
diagrams can indicate what to listen for, but ears have to be the
final decider.
I also use a shaking peanuts test for overall stereo object/image
placement accuracy. I use the term "sonels", or sound pixels to
describe the definition of a stereo image. Being able to distinguish 9
sonels across a stereo image is very good.
I've got a comparison of four-figure mics against my =A320 cardboard
Brinibox on:

Listen on your favourite playback system. My take is that the Brinibox
has a more even stereo spread, but a wider object angle. A fetch
difference of about 2:1.
BTW following that, I have two stereo puzzles for keen ears.
