The only real difference between a passive radiator and a port is the nature of the acoustic impedance conversion...
Close to the port opening and close to the PR there will be a clear difference. Unless the port has same opening area as the actie surface of the PR.

The ported solution will be more sensitive to nearby objects/surfaces.

Not a very big thing but if you get close to the back wall it will give different results by this mechanism.
