Soaked Chip Smokers vs Pellet Smokers

I have always used a charcoal smoker and use wood chunks soaked in water with it. I keep a bag of hickory, mesquite, and apple on hand and sometimes mix woods together. I purchased a metal box and a small bag of chips, soaked the chips and put them in the box and then the smoker, but went back to the chunks, more smoke and lasted longer, JMHO..........
