Wood is good when the power is down, esp when it's down for days at a time. But there's also on ongoing search for decent wood. If you've got money, you can pay for someone to cut it, split it, and stack it in your shed. Otherwise, it's scavenging and doing it yourself. But unlike pellet stoves, they will burn any kind of wood or woodlike material that you can fit inside, in a pinch.
Pellet stoves are much cleaner than wood stoves, but when the power goes out, it's just a chunk of useless hardware. (When is someone going to come up with a solar-run fan and auger?) And the price of pellets is going up with the downturn in the logging industry. Which also brings up the point that pellet stoves only burn pellets.
