Looking at BOV's. Is there any advantage of a vta bov over a pb bov?

BOV sound. That's about it. Plumb back or recirculating valves will actually make the car "peppier" because it doesn't "blow off" the boost, but recirculates it so your turbo doesn't have to re-spool the boost lost through the BOV.
