1. Cardioids will be roughly 1.7 times the distance of Omni's to achieve
the same ambience. 5' in Omnis = 8.5' Cardioids.
2. Cardioids at a close distance exhibit a proximity effect. They also
posess off axis coloration.
3. You will have a greater choice of stereo arrays with the Cardioids.

Since this list is so dead lately, I thought I'd go slightly off-topic.
The Five Browns are appearing on the Today show Saturday
morning (probably after 8:30am on NBC) and on Breakfast with the
Arts, A&E, Sunday morning sometime between 8 and 10am.
The Five Browns are five people (mostly women) who all play piano
at the same time. They arrange the pianos in something of a
pentagram.
It's different, to say the least...

A couple of additional thoughts on #2 below -
Proximity effect is a reality with cardioids, but usually does not
become part of
the equation so long as the distance is measured in feet.
The off-axis coloration of a directional mic varies greatly from model
to model.
Many cardioids sound wonderful on-axis, and when used close enough to
the
source (like, measured in inches) the off-axis response is not very
noticeable.
But, when used at distances measured in feet, the off-axis source level
can be
almost as loud as what's in front of the mic. In this case, off-axis
coloration can
and often does result in a lousy recording. You can predict which
cardioid mics
have good off-axis sound. Just look at the polar frequency response
charts. A
really good mic will have response circles that are almost the same at
all
frequencies. A lousy mic will have response circles that vary greatly
from
frequency to frequency. Compare a DPA 4011 with an AKG C3000. Both are
good mics, but the difference in off-axis response is considerable and
can be
easily heard in the recordings. Off-axis response is one of the main
differences
between how various mics sound when used for audience recording. It is
the
main reason folks will spend big bucks on mics (whether that is
understood by
the purchaser or not).
