I'm a die-hard charcoal user and probably always will be. But even there, I've not found anything superior to Webber, and most far inferior. And just from an engineering standpoint, look at the quality construction. The only way I could get a grill more to my liking would be if I had it custom built from boiler-plate steel, lined with fire-brick, and then with a reflective inner surface. And it would have to be parabolic, with a very large focal point for the reflected heat. And the outside would have to be painted with heat-proof paint to rustproof it. And then there would have to be an inderect fire-box with a channeled plenum to direct smoke to the food. And of course air control for maintaining correct temperature would be crucial.
I neither have time or money for my dream barbecue grill/smoker. But the Webber comes very close to what I would build, and probably does it better.
