Parker,
I use Eastern North Carolina vinegar based Dips (Sauce) differently than thick/sweet/tangy tomato based sauces. In my opinion thick/sweet/tangy/tomato should be used as accents as they tend to overpower, masking, as opposed to enhancing, flavor. Eastern North Carolina, used sparingly, enhances and compliments as opposed to overwhelming.
I, mainly, use Eastern North Carolina Dip (sauce) with pulled pork and/or whole piggy. My technique is, after pulling, sprinkle a little Bob in Ga Dip on the meat to keep to keep it moist. The salt, black pepper and crushed red pepper, used in moderation, intensify flavor, the vinegar help cuts the greasy mouth-feel of the pig fat and let the flavor shine through.
One important thing I learned from Bob in Ga, past master of the whole pig, is to mix in all parts of the pig. With whole pig you achieve balance of flavor and it's a slightly different experience than eating individual parts of Mr. PIG.
I prefer, as I mentioned, Eastern North Carolina, which contains no tomato or sugar. The recipe I use came from the aforementioned Bob in Ga who, obviously, lives in Georgia.

. I'm a fan of mustard based South Carolina style BBQ sauce as well. I'll include both recipes at the end of this post.
To be entirely truthful, there has been one instance where I used thick/sweet/goopy BBQ sauce on whole piggy. That was the time I used an unfamiliar cooker with an odd spinning grate set-up and 6-food exhaust that made it near impossible to control the fire. That poor piggy looked like it had been cooked in a forest fire then run through a tree shredder. Talk about BBQ sauce covering the sins of the cook.
Dave Lineback, who is an information resource on North Carolina style Barbecue, has a number of NC style sauces on his very enjoyable, and informative, web site
The Lexington Collection.
In rereading my post I realize I slightly contradict myself. I use all types of BBQ sauce sparingly, the main difference, for me, between tomato based/sweet and Eastern NC is that I add a modest amount of Eastern NC to pulled pork before serving, whereas I would not add tomato/sweet BBQ sauce to meat before serving.
Coming from Mr. Nothing says Excess like Excess, it may be surprising, but I suggest moderation in all things BBQ sauce.
Enjoy,
Gary
