I bought a Kamado Akorn grill last December and I absolutely love it! Before, I was using my Weber Kettle for all my grilling needs and for smoking, using my Brinkman Trailmaster horizontal. So as for the gas grill question,I haven't used one in about 7 or 8 years. The Kamado Akorn, I use all the time now. I bought the Akorn because it was way cheaper than the ceramic egg style grills, and I didn't know if I would like it. Now, I use it all the time, for most everything. The only thing I gave up from the Trailmaster was space. I do love how much you can cook on the horizontal smoker. I would cook for most all my neighbors because I could. For me and my family though, it was just too big and I didn't feel I was utilizing it's potential. I love stick burning. But the Kamado Akorn just made more sense for me and my cooking.
They are definitely worth the money and, IMO, much, much better than a gas grill. Sorry to ramble on....hope this helps! Smoke on, my friend!
