It’s the same controller as your blaz’n. Really, i don’t think there would be any performance difference. If you like the way your blaz’n cooks I expect you’d like the way the p&s cook.
I think you’re paying for a different form factor.
Those controls are made by the same company, but require adjusting to the units they are used for. Such as pellet feed rate, algorithm, shut down algorithm, temp probe adjustments etc. Thus performance may be due in part to how each company programs their units. In theory, they can be set to perform the same way. (may be supposition on my part?). Also possible that the manufacturer of the control may offer different performance parameters to choose from?
BTW Danson uses the same control on the Louisiana units. Now having said all this; it is possible that the Chinese have already made look alike copies of the Roanoke controller--meaning I could be very wrong about all of the above.
