Clinton County, Michigan
The PRN number does not relate to it's position, at least not with any of the recent changes. https://en.wikipedia.org/wiki/Wide_Area_Augmentation_System#:~:text=...
East to West order : 138 was the farthest East, then 131, 135(new) in the middle, 133 farthest West.
I don't know if any one is better than another.
