Actually, the PV is a one time reference, when you create it, so it really doesn't matter how you reference it. After that, it is found by the unique identifier that's written in the PV header information, it's UUID; the PV name can change, but it will always be found by its UUID. So, use either; It really doesn't matter at all.
