Not really. Higher order AMB will give you much better results.
There are not so many options. The following provides some
info on how they compare:

Hi Fons, this is _great_!

Any graphs of the performance in elevation != 0? Ie: plots, of, say, "T"
at different frequencies? I'm really curious...
Any information on how the measurements were taken?

But a few weeks ago I did a recording on a historical marketplace with it
and additionally with my "real-head-binaural" (Roland CS-10EM) in-ears
microphones.
The blackbirds in the tree above I can very clearly and precisely localize
with the Rolands, but not with the AmbiX-B-format. What a disappointment!
That is to be expected. But:
- The real-head-binaural is optimised for *your* head and ears. It may
not provide the same result for other listeners.
- It's also not possible to render this with head tracking, and
conversion to non-binaural formats may be problematic.
To get really good results when converting to binaural you need higher
order AMB. First order can be optimsied but even then it is really a
very delicate compromise between conflicting requirements.
But what would you choose? And always be aware of this is a unique and real
"once-in-a-lifetime" chance!!!!
I'd go for the Eigenmike or Core Sound's Octomic. And of course if you have
some spare channels. add some classical stereo setups.
It would also depend on what is the intended use of these recordings.
Do quantum computers make any noise at all (except for the cryogenics etc.) ?
