Angle is the same, as you can see in nuwave's picture, so assuming that the string is perfectly flexible, you will have exactly the same force on each of the strings at the nut. It is based on the angle, which is set by the headstock's built in angle.
Strings are not perfectly flexible, so while you are not changing the actual pressure on the nut from each string (more or less, given the angles are all roughly the same), you will see variations in the shape of the contact pressure patch if you were to map the pressure field of the string in the nut. I'll see if I still have the mappings I did on this about 6-7 years ago.
Honestly, the stiffness of the string, the string gauge, and the pull angle (horizontally) of the string have a greater effect on this than distance behind the nut if the angle (vertical) is kept the same.
But everyone has their own preferences and experiences these things differently.
That said, my Fodera was ordered 3+2 because I've never personally experienced much/any difference in 3+2/2+3. But I ordered my fretless 2+3...because why not? "Tighter" feeling B strings are more important to me on fretless, so why not experience the mojo/juju, whether I believe in the actual physics or not.
What does this mean to you?
