I cooked these the exact same being indirect with drip pan with water and apple juice over hickory chips. Only difference being the types of rub. I tried to do a side by side comparison on both and since I heard that the picnic would finish sooner, I put the probe in it and monitored from there.
Here are pics of the cook which was at 240-250 degrees for about 10 hours. Both were similar in weight at a little over 4 lbs.
Picnic / Pork shoulder
Smoke ring on picnic
Both pulled with picnic on left and butt on right
My personal favorite sauce! Shouldn't I get paid for this promo! HAHAHAHAHAHAA It is really good!!
Again, picnic on left and butt on the right.
All in all there isn't a lot of difference. The most notable being that the picnic / shoulder was a little less juicy.
Both will make you beat your brains out with your tongue, but if I had to pic I would stick with the butt!
Again, to get them to the correct IT, it took about 10 hours.
Just depends on preference!
It definitely has her approval!!
