If resale is NOT an issue, IE you're going to keep the thing for 5 years plus, GO ford.
And you can put up with that stupid steering wheel position.

If you have $35k, XR6 ($10k better then the SV6).
If you have $45k, XR6 Turbo (in the real world there's not a HSV that can get near it).
If you have $55k, FPV GS (Oh that engine...yes, yes)
