I don't think there is a "right" answer to this.
So, I'd guess that the Smith you're considering will cost about $550, and the Taurus about $300. Ballpark difference is $250. I'd guess the Taurus will still do the trick - revolvers are generally pretty reliable.
- Most important, depends on your household budget
- Some people own a dozen guns, but won't pay more than a few hundred for any one - others own 1 or 2, but will pay $1000 for one; neither way is "better", just a choice, and an aesthetic.
If budget is fairly tight, and this is "the" gun - I'd just get the Taurus, or, a used S&W. For practical purposes, I think that would work just fine, and is about 1/2 the price. You can buy about 25 boxes of standard ammunition for the price difference and practice, or take a daylong handgun course.
If you have some extra uneeded cash, and think you might be shooting a lot, and would enjoy the pleasures of the Smith, then I'd get the S&W.
