it depends on what you are cooking. For me, brisket, turkey, anything you cook for a long time is best on wood. But quick stuff like steaks, fish, chicken breasts, hot dogs, and burgers, nothing beats the convenience of a gas grill. I'd put the big bucks in a gas grill and pick up a smoker for stuff you want to slow cook.
No reason you cant have a gas and a charcoal/wood grill. That's how I roll. But then again, I'm from Texas. We cook outside more than we cook inside even in the rain and bad weather.
X3000. Unless you are trying to win a steak cooking competition for 10,000 bucks, use a god damn propane grill. It's cleaner, quicker and coasts less, and it STILL gives you an absolutely delicious steak if you know anything about cooking a steak on a grill.
