nothing beats the results of doing it the real way, but in this wonderful day and age, I find it nearly impossible to devote the required time and attention to a wood/charcoal system.
Each has its plusses and minuses. An electric, like a Bradley is about as simple as it can get. Problem is that you are stuck with using pucks for wood. Propane is also in that "set it and forget it" system, and usually uses a water pan for moisture control. Both produce a good product.
It all comes down to what time you can devote, what features you are looking for, and what price range do you want to spend.
There are also hybrid systems like the Orion that is really a convection charcoal cooker that you can do some smoking in.
