When I was in the grill buying arena 2 years ago, I was looking for a single "do it all" grill. My gasser was nearly dead, so I needed something that could cook absolutely anything and everything I wanted.
I was looking at both the kamado and the pellet grills. Both had their advantages, and both had their disadvantages. I liked the kamado for versatility, I liked the pellet for ease of use.
I ended up going with Kamado Joe Big Joe (and later a Joe Jr) because there's basically nothing you can't do with it. Smoke, grill, bake, sear, it'll do it all. And at the time, I figured "hey, I homebrew, I will clearly sacrifice ease of use for versatility."
I'm still very happy with the purchase(s). The Joe Jr makes for a great weeknight grill for something simple like burgers, fish, or as a searing station for sous vide. The Big Joe has plenty of capacity and it's awesome for smoking.
But I'm finding myself ever more wanting to add to the stable, because the hassle of dealing with charcoal *every* time I want to grill is getting to me. I was thinking of a gasser just for convenience, but I think a pellet grill might be just as convenient and a lot more versatile in itself. Given that I can get a Green Mountain Grill Daniel Boone model (the bigger one) for only $600, I think that might be on my shopping list this summer.
After I buy a Big JoeTisserie, of course
Edit: Scratch that, the Jim Bowie is the bigger GMG. Still not too expensive relative to other (weber) grills...
