Problem is getting the perfect or near perfect role on them. With AB, shot package and rifled barrel, they are all the same. PC+1 benefits from higher RoF which imo is more important than a tiny bit of extra impact. Neither of them are fellwinter's with range finder though.
Actually, the Matador 64 and Felwinter has +3 more base impact than Party Crasher: Reddit HoW Shotgun Reforge Thread. Both will hit range cap with the right mix.
