I have a gas Weber (little Q120) and a couple of BGEs. I have also had one of those abominable big stainless 5-burner shrine to futility things in the past.
The BGE is far and away the best grill I have ever owned. If mine broke, and a replacement was twice the price, I would not think twice.
The charcoal taste, ease of use, high searing temps, range of accessories, relative lack of grease (a big one!), ability to use it as a "brick pizza oven", etc all are strong factors in its favor.
For those that like to keep up with the Joneses, there is always another, bigger, better shiny thing with a gas bottle at the back. Yours is great, it cost and arm and a leg, but his is better. Not so with the BGE. There's only one standard. You meet it, or you don't. Not that this matters to me, but it will to some.
My one criticism is that if I just want to cook 2 or 3 bratties, it's a bit wasteful in terms of time and fuel to fire it up for that. So I use the Q120 for that.
BGE all the way.
