I'm from Texas originally, so it's brisket for me and a looong way down for anything else.
In terms of other meats, prefer BBQ chicken as a distant second, then pulled pork, then turkey.
In terms of regional BBQ--Texas is king, but KC has a shout to be in the conversation. For chain BBQ, Rudy's in Texas is hands-down the best; but there's so many smaller mom n pop places all over the state that it's hard to pick on its own. Truth in Houston is good for non-Austin joints (too many of those to list); while Joe's KC (formerly Oklahoma Joe's) is my favorite in KC.
To our resident Bammer: I'll actually admit that Lawler's and the Bama White Sauce isn't bad--I wouldn't choose it over TX or KC, but it's unique in a good way.
Anyone who says Sonny's is comparable to Texas is smoking crack: they're totally different. Sonny's is Carolina-style and if that's your thing, that's all well and good, but it's apples and oranges.
Woodpecker's is my Jax area favorite; but Mission isn't bad either (for a chain). If we're in Gainesville, Hogtown in the downtown area was a pleasant surprise and I make sure to go on a gameday weekend a few times a season.
Actually do like the datil pepper/citrus sauces that are starting to become a thing here in the Northeast FL/St Aug area--it's our own unique regional twist and people are starting to get pretty good at it.
Sonny's is definitely NOT Carolina style bbq.
Carolina style is really chopped up similar to pulled with the sauce already mixed in, Usually, Vinegar based sauce.
Usually, can't get "Carolina style BBQ" with Garlic bread either. It's usually Hushpuppies and occasionally, corn bread.
If you don't know what "chow chow" is, then you've never eaten at a Carolina Style BBq joint.
I'm not a fan of todays "Pulled pork". It's dried out and loses flavor.
While In Texas, I did indulge several BBq places and enjoyed every single one although, I've never been a big fan of brisket. To me, the differences in Texas were the sauces. These places always have their own sauces and twist on sides. I'm not a fan of plain untoasted white bread though.
Still, It's a unique skill to smoke a piece of meat for over 24 hours and the flavor of the wood you smoked it with, doesn't overcome the actual piece of meat. Texas seems to have perfected that process. I see rookies all over smoking brisket but all I can taste is Hickory or Oak.
Woodpeckers has the "Fatty brisket" which is the best of you're a Brisket fan.
Someone mentioned their sides and I have to agree. I've eaten there so many times now, I'm sick of their same sides.
