I believe it was Mama Asid from Mama Asid's Entrepod Asked about ceramic cookers. I do not have any personal experience with them. I do know that a lot of the competition cooks use them for cooking their chicken.
In the past I have used 3 Weber Smokey Mountain (WSM) cookers in competition. They are "bullet" smokers like the ceramic cookers like the Big Green Egg or Komodo. Unlike the ceramic cookers the WSM has to be insulated from the wind. A barbecue friend of mine Ray Lampe aka Dr BBQ uses the BGE as his main competition cooker.
Currently I am using the Fast Eddy Cooker (FEC100) made by CookShack. Its not that I didn't like the WSMs because I do. However, on the competition circuit, after two or three days, picking the WSMs up and putting them in the trailer along with tables, chairs, canopies, etc got to be a chore. The FEC stays in the trailer. BTW the FEC100 is a pellet cooker. It uses food grade cooking pellets in place of charcoal to generate cooking heat.
I have not been paid for any of the endorsements of the above cookers or web sites. The opinion are my own.
