Compare the peak gains and the beam-width of the specific channels most of interest to see which might offer an advantage over the other. Keep in mind that the presence of secondary lobes might offer the opportunity for usefulness----or mischief.
Longest range is typically associated with higher gain as it allows the antenna to gather a bit more useful signal power than the lower gain antenna. Having a rotor is a real plus when dealing with the most directional antennas.
