Default Vertical on a tower

Why? Doesn't make sense. If the vertical is best for
transmit, it should be the best for receive 98% of the time.

Nope. Verticals are notorious for picking up local man-made noise.
Man-made noise starts out with random polarization but the horizontal
component is quickly "shorted out" by the earth's conductivity, leaving
only the vertical polarized component. This is why AM broadcast
stations universally use vertical polarization; better groundwave
coverage. They are not concerned with skywave or local noise.

For skywave, either one works fine, but a horizontal antenna is quieter.
