I usually go by quantity, effort and method (indirect/direct):
Large/med quantities, med effort, indirect = Outlaw stick burner
Large/med quantities, low effort, indirect = Slugger Insulated w charcoal
Large quantities direct OR rotisserie = AZ BBQ argentine grill
Med quantities direct = gateway drum smoker
Small quantity direct or indirect = BGE mini max
Any meat on a stick = solo stove fire pit
and flavor profile: can't beat brisket on the stick burner, ribs on the slugger and chicken on the gateway!
