I'm cooking pulled pork for an event at work which gave me a chance to use my newly acquired (used) BGE and my WSM for a comparison overnight cook.
Loading Specifics
I filled the WSM with 2 pork butts and 2 picnic shoulders. I used some of my old Kingsford stash for fuel, with hickory and peach smoke wood. Piedmont pan with no water.
The BGE was loaded with 1 butt and 1 picnic (this is full capacity without a BGE ($$$) grill extender accessory). Based on owner recommendations I avoided briquettes and used Royal Oak lump in the egg. Evidently, the BGE can self extinguish if too much ash is generated. Smoke was from hickory and cherry wood.
Advantage WSM - Twice the base capacity of the BGE and the ability to successfully use a variety of charcoal types.
Start-up
At 10:00 last night, I Minion'd both smokers using 8 Kingsford briquettes in each. The BGE rapidly came up to target temperature and locked-in near 250F within 30 minutes.
The WSM slowly came to temperature, it was in the 175F range when I went to bed at 11:30.
Advantage BGE - For faster start.
Overnight Temperature Maintenance
I awoke around 3:00 a.m. to check smoker temps. The BGE was still at 250F. The WSM was slightly higher, but in my target range.
Advantage - Even
Morning Temperature Adjustment
I rolled out of bed at 7:30 this morning. The WSM temperature was at 230, and the pork was working through the plateau at 175F. I bumped some ash with a poker and opened the lower vents slightly. Temperature remains steady.
I was slightly horrified to find the BGE in the 175F range this morning. I fully opened the top and bottom vents without much temperature change. At 8:30 I opened the lid and tried to poke at the charcoal to remove some ash. This was not very effective because the BGE must have a "plate setter" accessory installed in order to use the egg as a smoker.
In order to reach the charcoal, I would need to remove the meat, remove the fat-filled drip pan, and remove the plate setter for top access. There is no other way to reach the coals. Temp is now at 190F, so I am going to disassemble the BGE to add charcoal.
Update: At 10:00 the WSM meat was at 190F and ready to pull, smoker temp was also dropping. Foiled pork and placed in cooler. BGE is up to 275F smoker temp after adding a big load of fresh RO lump. Very little remains of the big load from last night. Meat is working through the plateau to 177F.
I removed the meat from the BGE at 12:00 and wrapped held it for pulling.
Advantage WSM - For effective overnight cooking ability.
Cooked Meat Quality
There was no noticeable difference in the flavor and texture of the meat.
Conclusions
From my results I conclude that the WSM is a better cooker for overnight low & slow cooking. Beyond price, the superior capacity and temperature reliability of the WSM beats the BGE.
I will admit that I might have bought the BGE hype about infinite cook times with minimal charcoal. I filled the charcoal chamber to the top, but could have stacked it higher and possibly achieved a successful overnight cook. There was also an issue with the dome thermometer on the egg. I think it was burning 25 degrees higher than indicated (comparing Maverick to lid temps). This could also help explain the fast burn.
