In the case of that 160 meter dipole it was almost always better as a
receive antenna for 80 meters. It was better at rejecting ferocious
local QRN than the 80 meter inverted-V. Absolute signal level always
dropped owing to the mismatch, but the noise level dropped even more
improving SNR (from really deaf to pretty deaf). I am sure there were
cases where the 80 meter inverted-V was better, but that was the
exception not the rule.
I agree that Ken has the nice problem of having lots of antennas to
chose from for RX :-)

At N6RO's superstation (among other things, it was the antenna labo of
ARRL Antenna Book Editor N6BV, who lives 100 miles away in the city of
San Francisco), Ken patches lots of antennas to his operating position
for 160M contests for use as RX antennas. The reason is simple -- the
elevation, and even the horizontal direction at which signals arrive
can vary widely with time, based on propagation. Ken is a very smart
engineer, and a bunch of very smart engineers and operators are on his
team.
