The question that needs to be asked is does the food produced in an SI smoker taste better if it has an auber attached versus one that does not? I have not heard nor seen any evidence to support it if it does. Anybody ever do a side by side comparison? I haven't seen one. So long story short unless the food is tastier then I'm good with my standard #3. Others will see it differently and some actually need the precision the auber offers but for smoking butts, ribs, brisket, etc. Its not a must have. Just my 02 cents.
Unequivocally
NO. The PID control is absolutely
not about taste; it's about convenience and precise control. You will never be able to tell any difference in food smoked in a standard, or D-model smoker.
Rock on with your standard 3!! If you're happy, that's what counts! Just respect that, just like the whole Chevy/Ford argument, some of us really like to know that we are holding the temperatures we set. And, for those of us that smoke things that need 2-3 different profiles (such as things like Canadian bacon), we can set the changes and it will automatically follow the program - no manual changes! Plus, for low-temp smokes, like for jerky or fish, you won't have to worry about the spikes above the set point ruining your meat.
That's it, in a nutshell! It's just a matter of preference, not a matter of right/wrong, better/best!
