I have had my bsk for about a month now, I have cooked chicken, brisket, ribs, mooinks, fatty's, and steaks....
I have nothing to compare it to but the unit is well made, holds the heat extremely well, after doing a 650 cook for steaks, I closed it down and it stayed in the 400 range for at least 2 hrs.
The brisket and the ribs I cooked at 225-250, it held temp with very little fussing with the outside temp around 50, I even went out for a few hours and found it just like I left it.
I was afraid of having the ceramic crack since I have a small deck I need to move it around after cooking so the BGE made me nervous.
all in all I am very happy with the unit and would highly recommend it
