If you compare Core Sound OctoMic's first-order polar patterns (e.g., omni, cardioid, hypercardioid, dipole (figure-8) to the best ones from microphones that tapers here use, you'll see that OctoMic's are better.
Here's one: Omnidirectional
Attached are two polar pattern graphs. One from OctoMic, and the other from a very popular mono mic used my many tapers here.
On request, I will post similar pairs of patterns for cardioid, hypercardioid and dipole (figure-8).
