Depends on what kind of hunting you like to do. If you like to spot and stalk then I think Central California can't be beat. Big hogs (to 500 lbs) in fairly open oak foothills, perfect for spot and stalk. If you want some wild action with dogs and spears/ knives etc. then you can't beat the South (Tenn.). It just depends on what you're looking for. As far as guides there are plenty to be found, and prices can vary greatly.
