One additional comment:
At the very low end, the Zoom F8 is roughly 15 dB worse than the HV-316.
As you add gain on the F8, the errors get more and more audible.

A comparison of fifteen ambisonic microphones
When recording the self noise of an OctoMic using the
Millennia Media HV-316 and Zoom F8 (both with 30 dB of
gain), while the time domain noise levels look roughly equivalent,
their noise spectraare quite different. That's what accounts for
the degradation when using the Zoom F8.
At low frequencies (below 250 Hz), the F8 is five to ten dB worse
than the HV-316. At higher frequencies (1 kHz to 20 kHz) it's around
5 dB worse.
You can see the noise spectra here:

So the Zoom F8 penalizes mics that use low sensitivity capsules. It
makes the self noise sound much worse than it really is.
The folks who ran the comparison test seem to have overlooked this.
