I'm trying to choose between two different electric smokers. One will adjust up to a top temp of 300* while the other will only adjust up to a max of 250*. I plan to cook a lot of chicken and some turkey on this thing. How important is the capability to get up to 300 instead of 250? Will I notice a difference? If I go with the 250* model will I end up wishing I had the 300* model?
