Vertical smoker vs Horizontal smoker
Vertical Smokers (including pellet, charcoal, and electric) use a "heat rises" design where the fire is directly beneath the food. They are excellent for small spaces and "set-and-forget" cooking. Horizontal Smokers (Offsets) use a side firebox to pull heat and smoke across the meat. They provide the most authentic BBQ flavor but have a steeper learning curve and require a larger footprint.
