I would experiment with several types of wood. Combinations of different woods contribute unique flavors to anything you smoke. Personally, I use mesquite, hickory, cherry, apple, peach, alder, maple, grape, pluot, mandarin, oak and maple. All have very distinct flavors and I find there is no single best one or combination. For some foods that are more delicate in flavor I prefer the lighter flavors of the fruit woods over the more traditional hardwoods.While my gf prefers the bolder tastes attributed to the more traditional hardwoods(mesquite, hickory, oak).
As to what you may consider the best, that will be unique to you and your palate.
Mostly, have fun and keep on smokin'.
