I've cooked a lot on a friend's BGE and besides my Weber stuff I have a Char-Griller Akorn. They're very different to cook with, but I like them.
The positives about them:
- They're insulated so weather isn't as much an impact. And to be honest, the insulation helps the cooking environment as well. When grilling with my Akorn, the heat stays in the chamber, and the grill doesn't heat up the working area so much. Right now it's 95 degrees with 70% humidity, so I can really tell the difference! Standing in front of my WSM or OTG is very uncomfortable right now.
- Fuel usage is much more economical: I can use half a Weber chimney of lump for grilling a meal of veggies, burgers or steaks.
- I have the smoking stone for my Akorn. It does a very good job as a heat deflector, and I've cooked a couple of pork shoulders and babyback ribs on it. But it does a great job as a charcoal-fired oven, too. I'll bake pork tenderloins or beef roasts in it at 350 or 400 and the temp is rock-solid stable.
The negatives:
- You can overshoot your temp VERY easily, and once it's racing, you can't stop it short of closing the vents and smothering the coals. Wide open, my Akorn will shoot from 400 to 650 in a heartbeat. To do low/slow, I never crack the vents past 1/2 of "1" setting.
- Specific to the Akorn: the cast iron cooking grate arrives rusted. Forget about seasoning the thing, if you even look at it, it starts rusting again. Fortunately the aftermarket has steel replacements.
I would suggest you try an Akorn first. The price is much less than the ceramic kamados, and outside of the insta-rust grate, it's decently put together. I can often find the Akorns on sale locally between $50-100, simply because of the rusting grate issue.
