If you have a proper-working balun, it makes no difference. As Tree said
voltages and currents are equal or nearly equal in both halves of the
antenna.
If you don't have a balun and happen to have a bad combination of feedline
shield electrical length, there can be quite a bit of difference. Which side
should be where would be random luck.
Since the dipole is low, and electrically very close to other objects,
length is also a matter of what happens to be around the antenna and how it
is installed, so you would just have to experiment from the theoretical
length of about 468/F...especially if you have no balun.
