Hi Ben,
We set the steps so that you would never be more than 2 dB off. That
is really a pretty small error. If you think you will have strong
signals in a bad RF environment less gain is infinitesimally better.
If you are going to have weak signals at a distance in an RF friendly
area go for a little higher gain. In reality, you probably can't tell
the difference with either setting. The various RF stages are pretty
stout.
Best Regards,
