Sorry it took me a day to get this and I see you've received several
answers already.
There should be at least some difference in SWR and or output.
The SWR is straight forward, if the SWR is the same then pick the
setting that gives the highest forward power. If that too is the same
then pick the setting that has the "largest output capacitance"
according to the my manual.
