I moved your other thread, but now that I see this one, I'll just delete it.
I didn't answer the survey, because the answer "depends"
SP owners are loyal, and they've been around longer, so more people know about them.
Cost of ownership? Well go price wood and gas for the SP.
Durability? they're both the same, chain driven smokers that require some upkeep or they break down. The FE's have an auger and ignitor system.
Effectiveness. If you TRY to run the Sp on all wood, you'll get a lot of ash and spend a lot of time keeping that up. Most SP owners run it on gas, but they certainly don't advertise their BBQ is "gas cooked".
FE's are 100% wood.
Does that matter? to some yes, to some no.
cronyism listed some good questions to get answers.
I've cooked on both, but not as a restaurant owner, so I think you need to hear from them.
And do call CS, as for John Shiflet, he's sales. He can try to hook you up with someone using them in your area.
