I have a charcoal grill with a wood fire smoker box which I love to use.  Using the smoker box produces great smoked meats but it can be an all day process of adding wood and constantly adjusting the air intake vent or the chimney.  

My new Masterbuilt 30 inch digital smoker produces meats just as delicious with a whole lot less work!  I don’t think I’ll ever go back to the smoker box.
