Well.....frankly, for 4:3. I confess I've tended to interpret generic intervals
in terms of smallest numbers; and while it may not be just (heheh) for one
to think of 27:20 as a "4:3 too wide by a syntonic comma," I think there's
probably at least somewhat of a psychoacoustical basis for doing so, and
of course there's a cultural basis for doing it, since the omnipresent 12-tET
represents both 4:3 and 27:20 by a single interval which is much closer to
the former than it is to the latter.

However, I'm certainly open to _any_ interval, 27:20 included, being
considered as distinct and viable in its own right. I'm grateful to have had
my ears opened to my own prejudice (commaphobia?), because it brings up
a notion I've never really considered before, that of two opposing schools of
thought: one, in which the comma is feared, hidden, made to disappear; and
another, in which it is embraced and celebrated, or, at the very least, accepted
without judgment as a part of a "value-free acoustics."

Now, I must go away and ponder these things.
