While living in Virginia, the rub I was taught by an old gentleman, who smoked more pork in his life than we could even think about (worked for Smithfield hams), was chili powder and lemon-pepper. It is my go to rub, but there are still some fantastic ones out there that I am using, Simply Marvelous, John Henry's, Dixie meat rub and even Yard Birds. While I have never used Yard Bird's on pork, I think it is fantastic on bird. My wife who does not BBQ, but uses the oven to cook bird, uses Plow Boys almost exclusively. I have business interest in any of the products mentioned, other than as a satisfied customer of all products, and who will continue to purchase the said product.
Now back to topic. Never had pork neck, so ya can send some this way to verify your statements
