I make grills for a living. Big Argentine wood-burning ones that get installed into counter-tops or chimney systems. For what its worth, I think the BGE are pretty good and very versatile. They do a lot of things decently. I also saw the Kamado Joe version and thought it was very nice. I may lean that direction if buying a kamado type grill.
The thing to keep in mind with all grills is the more well rounded they are the less likely they will excel in any one area. There's a give and take at play with grills and smokers. I don't think the kamado types or any gas grills hold a candle to our grill in terms of grilling. (I don't like the pellet grills for grilling at all) However we can only draw a slow cook out of our grills and not truly offer a smoking option.
Think about what you will do the most with your outdoor cooking options. If you primarily grill, look for a strong robust grilling frame that gives you the grilling space you need, minimizes flare ups and helps you to to burn wood and charcoal efficiently. If you will primarily smoke, get yourself a solidly made smoker and then a cheaper, smaller gas grill on the side when you want to fire up a couple burgers and dogs. If you will truly mix it up, than a kamado style grill is a pretty decent option.
And of course pricing will dictate a lot as well. You can spend a fortune or a couple hundred bucks. You mostly get what you pay for but sometimes you can find a decent deal. But when you are saving, no matter the quality, the lower the cost the more mass produced and likely sourced from China the grills are. We make high end robust grills, but our costs are primarily on the high end because they're built here in PA and every grill has some built-to- order aspect to it that makes it a one off construction instead of fabricating it in larger quantities. That drive up the costs and makes custom grill builders more susceptible to material price fluctuations. But we can build exactly what the customer wants. Hope some of this info helps.
