@squinney,
Also, not a big fan of pulled pork, so I wouldn't pick Carolina, north or south. And the Texas stuff I've had wasn't even edible, they often use mesquite which imparts a horrible bitterness to long smoked meats. So from your list, I'd pick KC.
I make a mean batch of ribs myself.
Some may laugh but California has a barbecue style all its own. It's not barbecue but it's not grilling either. Santa Maria style barbecue of tritip (beef), served with hot salsa and pinquito beans, salad, toasted bread, and maybe mac&cheese. It's an experience.
