Don,
Great question. Personally, I choose gas over charcoal when grilling anything under 20 minutes. Meaning most direct grilled foods because gas is much more consistent. When grilling for large crowds and family parties I need as much consistency as possible. That, being said, there is nothing better than a perfectly grilled steak on a a legendary Weber kettle!
Now anything over 20 minutes, indirect cooking I prefer charcoal. I love the flavor, taste and depth charcoal brings to grilled foods. Plus I love the ritual and the anticipation that comes along with perfectly grilled, bbq'ed and smoked foods with charcoal. That being said, I am currently using my Summit 670 along side my Bullet's almost every week to smoke ribs, shoulder and etc. and have found the results to be tremendous. To the point that my guest cannot tell the difference between food I have smoked on my Bullet's and my Summit.
I guess the jury is still out!!
What about you?
