If you are referring to flame cutting, it should be about the same, being a very similar frame size.
The firing pin setup is different. I ran several thousand rounds through mine, The firing pin return spring broke, and sometimes the firing pin would stick in the primer indent and keep the cylinder from turning. Tilting the gun would allow the cylinder to spin. Taurus fixed it right quick. That technically is something that would not happen on older smiths, though many new smiths use the floating firing pin now.
The Taurus guns do not seem to wear as nice as Smiths though, if you are gonna run thousands and thousands of maggies, the Smith would be easier to fix locally, and has an edge in durability. People who ran Taurus in competition seemed to wear out things like hands and pawls more frequently. If you are gonna shoot something on the order of a couple of thousand rounds in its lifetime, and would have to ship back to the factory anyway if something broke, the Taurus would be okay.
