I've considered a gas grill, for convenience, but all I have is the 36" Blackstone flat top griddle, which is fun and can feed a crowd, and the KJ. Years ago I had several grills at one time, each serving a purpose. The wife is not a fan of the obsession and utilization of space. I have to say she has convinced me, it's just too much, looks like a damn junk yard or something. The KJ is pretty cool in that it has an inner rack, place the half moon grates on the lower for searing things such as steaks, the upper for slower cooking. For low and slow, cooking upper rack, there are 2 half moon ceramic or clay plates you can place on the lower rack between the coals and the meat. Sort of indirect cooking. I think the outter shell is steel, painted. But it is lined with ceramic on the inside. Once the ceramic heats it holds it really well. The entire thing is really heavy, sitting in a base with wheels. It's nice, they are kind of expensive. The cooking surface is not as big as I would like sometimes. I've also found that the depth, if you're cooking say only 2 steaks the coals are too far away from the grate even in the lower rack for good searing. I like my steak burnt on the outside, still kicking on the inside. I have to add a lot of wood charcoal to achieve that combination. It's kind of a waste, although you can close the vents and use the remainder of the coals next steak time. Speaking of venting, it is pretty air tight, no leaks that could mess with control of the burn. Lid seals well, hit the gas vent on the bottom, hit the brake vent on the top. A little getting to know with time and use, those two vents provide consistent control of temperature. All things considered, I recommend. Given the ceramic nature of it, they say you can do a really nice brick fired oven style pizza in it, with the addition of a pizza stone. Have yet to test for that purpose.
