There are several types of grills and these are charcoal, gas, wood, electric smokers, open fire grill, and pellet grill. Each of them offers different benefits. In terms of comparison, pellet grill is still superior because it is the combination of all such grills. You can use it to smoke that way charcoal grill does. You enjoy the wood flavor of wood grill using pellets, and it is also electrically and electronically-operated.
PID: For the most precise temperature control, some pitmasters feel that a grill with a proportional-integrative-derivative (PID) controller is the way to go. A PID controller uses algorithms to keep the temperature within a couple of degrees of the setting. It doesn’t use fixed cycles to release the pellets. Instead, the controller only adds pellets when it’s necessary to maintain the desired temperature.
I live in Florida (Ocala), and I would like to grill, but I am undecided what to buy. I would not use the grill everyday. I am not a ‘griller’, but I do enjoy grilling simple meats, hamburgers, pork tenderloin and chicken; perhaps smoking a 12 lb. turkey for Thanksgiving and Christmas. I have no knowledge as to grill veggies or fish. I am an ignoramus! I tried, but I couldn’t detect them among the ashes!
