Outdoor cooking - Barbecues, Barbecue, BBQs, BBQ, Smokers, Grills. And Ribs.

WSM is more old school and can be used as a smoker, bbq or grill.

GMG is more modern, less finickety but gives a milder smoke and works as a bbq but it does not get the same searing hight grilling heat of the WSM. But it is computer controlled and easier.

So if you want to be able to do more it’s the WSM but if you want simplicity of use it’s the GMG. I own both but tend to use the GMG more. This is also because my wife prefers the more subtle smoking of the GMG. Though there are times when I want the deep smoke of the WSM.
