My limited experience has taught me that it is
mostly related to your antenna system.
Sometimes a vertical hears what a horizontal will
not, sometimes the lower NVIS-type antenna hears
what the higher non-NVIS one (rare that anyone has
a non-NVIS 160M horizontal antenna) does not and
the opposite.
There may be other localized factors line-of-sight
to the particular opening that could impact reception
but what you describe sounds more like an antenna-
system driven experience than a minor geographic
difference.
Is there anything significant about your geographic
locations, e.g. water, mountains, heavy forestation,
industry, RFI more present at one location than the
other at certain times of the day?
Others may have different experiences but given
roughly similar antennas, feedlines, tuners, rigs,
and grounding systems you both should be hearing
most of the same stations.
