The only difference between the S&W and Taurus complaints seems to be that "S&W's service will treat you right". But you still roll the dice with S&W when you buy a new revolver.
You roll the dice with any handgun from any manufacturer. I suggest you use the search function as you will find accounts of Ruger barrels falling off, Glocks blowing up, Colts cracking frames and any number of other problems from just about any maker you can think of. Anyone can have a lemon. The measure of a company is how they treat you if and when you do have a problem. I can say from personal experience that S&W treats their customers very, very well. For that reason, I continue to buy their products. If you look at the Taurus complaints, however, they're not just limited to the gun itself. The biggest complaints that I see with Taurus is that their customer service is lacking, specifically it may take many months to get your gun back.
Having owned both S&W and Taurus revolvers (as well as Ruger and Colt revolvers), my take on it is this: neither is a bad gun. The extra money for a S&W gets you better fit and finish, typically a better trigger, better resale value, and better customer service. I, personally, quit buying Taurus guns after I found out what dismal resale value they have, I can afford to buy S&W and the benifets I mentioned earlier are well worth the extra cost to me.
