Rob - A lot of good information here. I have been mulling over my reply and doing some prowling around the web gathering info. One source is run by a fellow named Meathead. Easy to find.
I have done years of smoking on a weber kettle and then an offset smoker. The smoke profile is definitely different than with an electric. Wet chips always went into the Weber with the coals banked on one side of the grill. The offset burned a mix of lump mesquite and chunks of hardwood. The smoke exiting the chimney when visible was very wispy and light. Meat came out flavorful with a nice mahogany color. On the Amerique, the smoke is a tad heavier, not wispy, sort of an opaque white. The meat comes out with a darker crust. Not bitter, just different.
According to Meathead, thin blue smoke it ideal, and can really only be obtained with burning wood as the heat source. In an electric, or any system with wet chips, the wood smolders, does not burn, and the chemicals it releases effect taste. Because there is no flame, the particulate matter that makes up the smoke is larger and that gives it the whitish color. Actual wood combustion has smaller particulates and thus the smoke is thin and blue (some of the time) depending upon the smoker system. The hotter the fire, the thinner the smoke.
I went electric because I was tired of having to tend the offset on long smokes. I loved the flavor and and the color but I can achieve similar in the electric. Very little wood, just a couple of ounces. It pretty much comes down to your personal preference for the system, how it will be used, and what research on your part reveals. And of course the budget.
Here is a link to Meathead:
