It is an interesting question, and it has some truth in it. Low temp settings led to some good, clean white smoke that create the flavor profile we expect. Varying the flavor by pellet (i.e. cherry, apple, or cooking pellets perfect mix) can change the smoke profile and taste of your meat. Higher temperature cooks produce less smoke flavoring but both toast and produce delicious, melt-in-the-mouth food. Many new grills on the market now come with innovative Smoke IT technology with PID controller. You can use your phone to control your grill from a distance. This Bluetooth capability with the fully digital temperature control system makes it easy to access the Pellet Alert System and PID Temperature Control. Pellet grills/smokers with PID controllers can be used to produce more smoke with some trade-offs. While smoke production is increased, the temperature accuracy will decrease. If you plan to use a PID controller with a higher smoke setting, you should expect larger swings in temperature. I don't think PID is the only factor: you must also consider your pellets and adjust them as needed for the desired results.
