I know the Weber Smokey Mountain is top notch. It is loved by everyone. You will never hear a bad thing about them. The same great Weber quality and function.
I don't know traegers real well. You can search for them on this site. They burn pellets only, so they seem limiting to me but they have their fans. I am acquainted with someone whose husband has one and she loves theirs.
With the weber, you can use wood that a friend or neighbor has trimmed from their apple, pear, peach tree or any other interesting wood. Free smoking wood is always good.
I, like many here, have the Masterbuilt 40" Electric smoker that has been very good. One complaint is that it doesn't put out enough smoke, but there are things you can do to increase that. Masterbuilt has a larger chip tray they send out at request. They burn chips so you can burn any chip, even if you have to make them with a knife. It can also use pellets. I use an amazin pellet smoker with my electric to assist in adding smoke, so that limits to pellets or sawdust if I want a stronger smoke. When researching, I read that the electricity for the masterbuilt was much cheaper than the coal for a coal and wood smoker. It is actually quite cheap to run. I think less than $2.00 per smoke. I bought it at Sams club for $299. I am not selling the Masterbuilt, but I know it so I am using it for an example. The Bradley is a well loved electric, but again it uses wood biscuits for smoke. That again seems limiting.
They will all do great for you. You just have to learn the unit with a little practice. The benefit of all electrics is you don't have to tend them as often as coal.
In the long run, you will always win. It will just take practice and there are people that can help. Find the units you are most interested in and post it on the smoking equipment forum and you will get answers.
