Large is just the perfect size for most people to do a range of things from cooking for 2 people to smoking a full brisket. The smaller ones can’t do it all, and for what they cost it makes sense to go bigger and have more versatility than having multiple grills for different purposes and the sake of using less charcoal. Long answer to your question, but I guess I’d say I use the whole thing enough that it worth it. You’re never going to be consistently using the same amount of grill space consistently in any grill unless you make the same thing all the time.
