I agree that Rugers are stronger than S&W, however, I'm just an average shooter and I'll never shoot out any of my Smiths. I thing that Rugers are fine guns, but the Smiths are smoother, and I've never had one that wasn't extremely accurate and that goes from .22LR, .38, .357, .41, or .44 Spl. I must admit, my SA Rugers in .357 are tackdrivers.
Again, you can't go wrong with either choice.
