The only difference in the signal level at the DX location will be the added
feedline loss of option B due to the slightly higher SWR. Obviously that
depends on the frequency and the type of feedline. In any practical setup you
would never detect a difference.
Otherwise, a good SWR is only important when transferring power from your
source, the transmitter, into the feedline. If the transmitter will deliver
the desired power into the feedline Z present at the transmitter end, and the
feedline is rated to handle the peak voltage of the standing wave then there
is no problem.
