When comparing the two with exactly the same head movement (5mm off centre) the parallax error is pretty much the same.
Absolutely, the same can be said of all scopes. But does that leeway that manifests as greater PX error if you aren't very careful about your head position have anything to do with the lens configuration used in FFP scopes? I seem to recall a few having problems with the FFP Leupold MK4s in this respect too.
