Here is a similar comparison at 20 feet with no mast.

And here are the same antennas with masts.

Based on these models, it appears to me that the different radial configurations will have different effects on common mode currents. As we can see without masts, the radial configurations have no real effect on the radiation pattern, only an effect gain with the shorter radials having slightly more (not a noticeable difference).

However, with the addition of masts, the two antennas have different radiation patterns. This suggests the different radial configurations will have different effects on said common mode currents, thus creating said different patterns.

Because of this, with various mast lengths/ground conditions/ect. it is possible that for some people the shorter radials will have better lower angle gain, and for others the longer radials will have better lower angle gain.
