You need to add a little extra time to the microwave route because microwaves are line of sight. The signal needs to be detected and re-amplified multiple times along the way. How much extra time? I don't know, I'm not an RF guy, maybe someone can chime in and tell us how much latency each amplifier adds. The neutrino route only needs a single detector at the very end, nothing along the way.
