I have several Taurus handguns. An 85, 94, 605, 606 and a 9mm Millenium. I've put thousands of rounds through them without any problems. I have a couple more on my gonna get list.
Having said that, with both guns being priced the same, i'id go for the S&W.
Not because of any quality issues but because the S&W will keep more of it's resale value.
My 642 is my favorite snubby.
