Many variations. 3/2/1 is a good starting point for someone starting. It’s all adjusting to timing for what you want. Competition style has their preferences which are not the preferences of my family. Wife likes them more like pulled pork and I prefer a bit softer than comp style.
I also like a good bark but no aftertaste of the smoke. I stay away from hickory, mesquite, oak and use a blend of apple/cherry wood. I do my own method of 1-1-1- 1/2 for mine and my wife’s goes 1-2-2. That 275 degrees- 190degrees, wrapped, warming tray.
Another variation that I alter time for is seasoning. When I do a batch of Cajun-mango, they need to be wrapped much longer for the mangos to break down and absorb into the meat. If a do a dill weed or garlic batch, they season up much faster
