Well .. an off set is a reverse flow as a reverse flow is an offset ................ previously all I ever had was an off set smoker ....now,since I now own a reverse flow offset .. there is really nothing like it ... no hot spots in smoker at all .. all cooks evenly ,, probably no difference of 5 degrees throughout the entire smoker ... only modification I ever made in my reverse flow is I raised up my fire grate in fire box .. cause on long smokes like butts .. ashes fall under it ,,, and temperature would drop.. and air under the fire maintains temperature ..
