Just my two cents, I have no experience on the PBC or a pellet pooper.
I wouldn't base my decision on which one does beer can chicken the best. I have the weber holder chicken stand and love the concept but spatchcocked chicken is also fantastic.
I know someone that had both a traeger and the PBC, thinned the herd and the PBC went on the chopping block.
No doubt if it was me I'd go for the RecTec, been wanting one since I first saw them.
Hope you like your decision. Can't wait to see some cooks on your choice.
