I read this entire thread carefully, and feel I must make a few comments.
First off, I've been shooting for nearly 40 years, and I've owned dozens of revolvers.
The wife and I are down to 26 revolvers as of this writing. Twenty of those are Smith & Wessons. As you can tell, we like S&W's, (but her favorite is a 1972 Colt Python, and mine is either a 1978 Dan Wesson 357 or a S&W Model 57 [.41 magnum].)
We don't own Taurus guns because, frankly, Taurus has (had?) a terrible reputation. I am sorry if that offends anyone (it will) but it's true.
Even though we own more S&Ws than any other brand, I would only trust my life to my Ruger GP-100. The reason is that the GP-100 has front and back-end cylinder lockup. Over the past four decades, I've noted the main reason for failure in revolvers is that they go "out of time," which simply means the cylinder turns somewhat sideways and binds up, rendering the revolver useless.
I've had two S&W .44 Magnums freeze up in such a manner. Both guns did so while shooting
.44 special ammo
I've also seen this in an old Ruger Security Six.
More recently, I had a S&W Model 28 bind the cylinder after shooting heavy .357 magnum ammo. Both the Ruger GP-100 and my 1978 Dan Wesson shot the same load with ease. The Dan Wesson also locks the cylinder front and back.
Additionally, the GP-100 has a massive top strap, heavy coil springs, and is undoubtedly the toughest double-action revolver made. The trigger pull can be smoothed by a gunsmith or a skilled novice.
Sorry for the long post, but I wanted to outline my experience in order to give a reason for my opinion. An opinion without knowledge is just an opinion.
