I bought the pro 780. I really like this size because I am able to fit at least two briskets and then several racks of ribs if needed. I love the app and the Wi-Fi integration although the app still has a few bugs to be worked out. So far I have cooked ribs and two briskets along with chicken several times. Even though it was my first time doing it they came out tasting like professionally cooked meat. Smoker quality is top-notch. So far I am very pleased.
