I've never used an Akorn, but I've had my WSM for over a year now and love it. A lot of us on here have them and use them successfully.
But like the others say, I'm just smoking with it. I haven't, or don't have any desire to "grill" on it
18.5" WSM ; Weber E-330 ; Weber Q200 (tailgating) . . . Guess I'm a Weber fanboy!
