Cherry's PBT is a bit smoother than their ABS, but not by a lot. Between NIB dyesubs and NIB doubleshots there's not a big difference, but obviously the PBT set will hold up much better in the long run because of the material is way more durable.
From my experience, the going rate for ANSI Cherry dyesubs seems to be $300 for mint and $400 for NIB. For ISO around $60-100 for mint, not sure about NIB.
