With the Traeger, the fuel is fed from the hopper as it is needed, so it is very easy to turn it on, get it to heat, cook whatever I want, and then turn it off. No fuel is wasted, and the cleanup is fairly easy.
The other thing is – as I mentioned before – although I have successfully done a reasonably long smoke on my kettle, it required more or less constant monitoring to maintain the temperature, so it is unlikely I would attempt this when I had people to visit. This is not the case with the pellet grill, which can be more or less left to itself (in fact, it is frequently said “if you are looking, the food isn’t cooking”).
Is this all just rationalisation to justify buying the thing? Perhaps, but I do think I am going to get good use out of it, and as it appears to disassemble into three portable parts fairly easy, it isn’t out of the question that it might get lent out occassionally.
If you are still reading to this point, you are obviously interested, so here is a video showing how the fuel system of a pellet grill works.
