What I like: Rapid and precise heating; Uniform temperature over the cooking surface; Simple to use and no flare-ups; Less mess than charcoal; Reduced cost over propane cooking.
What I don't like: The cover height over the grill surface needs to be higher to cook taller foods; There needs to be more, and more constant, grill heat to maintain a smoker box; Food lacks smoky flavor (chicken tastes more like it was oven-cooked).
