When it comes to cooking, grills are no more than tools. As long as the tool you have is functional, it's how you use it that counts when cooking. A taste test between rib-eye steaks cooked on a $1,600 Firestone Legacy grill and a Big Green Egg charcoal grill/smoker that was less than half of that price confirms this theory: almost all tasters preferred the meat cooked with the Egg.
Of course, the reason that tasters preferred the Egg steaks was because they had a slightly smoky/woodsy flavor from the charcoal, which was not present with the larger gas grill, and the tasters liked their meat that way. The point is that both grills performed well, cooking the steaks evenly despite their differences in price. The specific flavor preference of the tasters, while an interesting addendum to the gas vs. charcoal debate, has nothing to do with the functionality of the grill.
I'm sticking with my gas grill because I like the way it works and am not a huge fan of charcoal flavors in my everyday foods. But whether you like charcoal or gas, as long as you buy a well-made grill and not necessarily an expensive one, you are bound to have more than a few good meals.
