I'd probably look at what you wanted to cook,how much of it,and how often.
Now,I have a commercial version of the AQ,and a couple FEC s.
I love both,and if they'd let me take the traditional CS to comps,I'd love to.
As for wood for the AQ,it would cost about the same to cook a couple times a week, for a year ,as one cook in a Klose.
You could cook all night on a couple small fist sized chunks.
Maybe $0.25 at Home Depot,etc.
If you burned one lb pellets/hr and 40 lbs of pellets cost +/- $25,you can figure the math.
If you cook a lot,or divide a pallet with some other cooks,that is about your cost.
If you buy them a 20 lb bag at a time from a bbq store,maybe twice that cost.
As to "better " chicken skin,do you mean fried crispy?
The FEC can accomplish that,if you know what you are doing,pay close attention,and it is real important to you.
Just as a Klose can.
The AQ will produce good "bite through" skin,which is what most comp cooks try for.
I believe you can run it about 300º.
Chicken skin won't start to fry, until something over about 335º.
There is a lot of great comp chicken cooked at 225º-250º.
In any case, many people discard the skin when they eat,anyway.
I guess you need to estimate what percent of your overall cooking is going to hinge on "fried" chicken skin.
Seems like most folks get a smoker to cook low and slow,to break down collagen and render fat.
Yardbirds don't have much of either.
Given a choice of which to use on chicken pieces,for a 25 minute cook,I'd be more likely to fire up a Weber kettle.
Now ,if you cook lots of chicken pieces and open the door a lot to mess with them,the FEC has a much faster heat recovery time.
It would also be much faster than a Klose,as well.
Just a couple of thoughts.
