I have been very happy with my Yoder YS640, which I've had for close to 4 years. I bought it used from a competition guy. Like many others, I use it regularly for everything from burgers, dogs, and steaks, to competition meats and sides.
I came to the YS640 from a RF Offset stick burner. My friends and family cannot tell the difference between the two from a smoke perspective. I can, but I'm a BBQ nerd....however, I will tell you that the Yoder is the closest thing I've come across to a clean burning stickburner. I am not a fan of WSM, UDS, or anything with a choked down charcoal/wood chunk fire. I can taste in my food when charcoal is lighting on fire.
As to capacity, I have squeezed 10 pork butts on it at one time. Extremely tight, but no adverse effects, and I rotated meat during the cook. I think you could easily get 2 butts and 2 briskets on it. It easily cooks for my family of 4 and stragglers! lol.....
I can't speak to the P&S or RecTec, but the YS640 is solid and the new controller sounds great......
