Pros: temp control, lump usage, end product, ease of use, availability, information available
Easily the best smoker out there for under $400.00.
Its charcoal not electric, or gas, thats its 1st & biggest advantage. You are using a smoker, not an oven that smokes.
Great bbq flavor, a miser on fuel, easily holds 225 for 9-10 hours in all weather conditions.
I sold all my other smokers when I got the WSM, they were just wasting space since they were never going to be used again.
