I own both as well, and mostly agree.
I have a 22" WSM, so it moves the favor a bit more in that direction but pretty much everything still applies.
I will say that the "set it and forget it" nature of the PBC isn't always great. If you get a windy day, not being able to adjust it has its drawbacks. It took me a while to learn how to make it do what I needed it to do in less-than-ideal weather. The WSM's vent control is amazingly versatile and makes up for its slightly more complicated nature. It took me less cooks as a WSM owner to get the hang of the temp control than the amount of tricky weather PBC cooks it took me to be able to make it work. So I'd actually say the ease of use award goes to the WSM.
I'm 100% with you on the chicken. That's the WSM weakest area and the pit barrel's strongest. And my opinion on the brisket and shoulder is similar. I usually use the PBC just for the 65% time savings, but if maximum flavor and quality is what the goal is, I'll take my WSM over it.
I make ribs on both. Both are great, it's just a matter of what you want them to taste like. When I cook for friends and family, I usually toss some baby backs on hooks and hang them in the PBC. Most of my people coming over for dinner like the lean, charry, crisp type of bite. But when I compete, it's spares in the WSM. I can craft my favors, exact heat, bark, color and bite much more precise on the WSM. More versatility means more control.
I have the old 1st gen PBC, and like the porcelain coated newer ones. I didn't realize Noah switched to thicker steel too. (You sure it's not just the porcelain coating makng it seem bulkier?). Either way, I'm a bit jealous...
When people ask me which I prefer, I say it like this:
If I woke up hearing sounds on my deck that my PBC was being stolen, I'd yell, be angry and call the police. I'd probably replace it if it wasn't returned.
If somemebody was stealing my WSM? I'd come out shooting.
