Hi Nomamm, glad to have you joining the party. I have a RT 680 which is the older version of the Bull. I have found my pit to be spot on from a temp perspective and puts out all the smoke I need for our taste. I did not seal my door as some others have, and get some smoke seepage from the door, but that has not made a smoke difference on the food coming from the pit for me. I personally have never cooked on a Stampede so others can chime in with better info than I can provide. One thing to mention, there are other pit makers such as Memphis, who also do not have a stack but use vents built into the unit instead, and folks who have those cookers love them too. Good luck with your choice. There is no wrong choice, just the choice that is best for you and your needs.
