There's quite a bit more personal preference in this question than will be reflected in a simple set of choices on a poll. I cooked with a charcoal grill (I made myself from a paint thinner drum) for years, until propane grills became common. With our first one (a Sunbeam), I was sold. When it crapped out, I bought a Weber Genesis, and have never looked back. With me, it's basically about convenience, and I don't want or need anything more to do with the time or mess involved with charcoal.
But the whole cooking outdoors thing is more like a religion with some people than a pastime. My eldest son has a combination grill / smoker, and wouldn't touch a charcoal briquette with a ten-foot pole; it's lump charcoal all the way. I have no doubt that, with the smoker box, his charcoal cookin' machine is more versatile than my Genesis......but I don't care. If I ever decide to smoke cook, I'll buy an electric smoker, and that will be that.
In the meantime, I get along fine. I can do all the regular grilling, plus, with a little finesse, the Genesis makes for mean dry rub ribs. Was the Weber more expensive than other propane grills? You bet; and I willingly paid that going in. Grills WILL need replacement parts, and parts for any Weber are available in any number of stores around town, and a dozen on-line vendors. As I said, with me it's all about convenience.
