The backyard Jambos cook BBQ very well and do it just as well as their big brothers. In fact, my Jambo was right beside Tuffy Stone's big $15k Jambo in my last competition and I beat him. I came in third overall and he came in fourth overall. So, I think that speaks highly of the quality of BBQ that can be produced with one.
