Pn V. Pf
We have a PN (X-15) and I spend a lot of time on Specters X-30. I will say that though the PF clearly has significantly more room, I don't think that space has ever been an issue for either of us. That said, I will second the guy who said you really can't go wrong either way. If money were no object I'd have a new star and that PF is, shall we say, unique.
