The vanquish won the Dallas open by itself. Did infamous ever win before the update cam out? no. So it must be the gun
I really hope you are trolling… To answer the OP question you should go with whatever feels best in your hands and the shot quality you like best. Do you want a spool or a poppet? Thats the main question. Personally I prefer spools, so I would go with a Luxe, the Vanquish is a cheap re-make IMO and looks hideous. So if I HAD to choose between the LV1 & Vanquish (and yes I've played with both) I'd choose the LV1.
