Once you get the hang of it, a kamado is not really that difficult. With the right lump, initial fire, and vent settings, it will hold a stable smoke or reverse sear roasting temp for a long time with minimal adjustment. Dual probe thermometer with one in the dome really simplifies things. Then you also have the versatility to indirect cook wings and things at 350, pizza on a stone at 650, and sear over flames as hot as you would ever want.
I like the idea of a pellet grill for simplicity, but there's no way it would replicate my whole tenderloin or rib roast, lamb chops, etc reverse sear. I can set mine at 250 for an hour, pull and cover the meat, take off the cap and remove the ceramic tray, rake the coals, hit the intake with a blower for 20 seconds, and in a minute it will be 600 for the final sear.
