Pocket carry?
If so, consider the weight issues. The Smith is a lightweight revolver, and won't cause noticeable snags like the Ruger. The Taurus comes in regular and lightweight versions, and I can't vouch for anything on the Rossi.
If for holstered carry or for a "car gun," then weight is less an issue. Personally, I would look between the Smith, Taurus, and Ruger, with preference going to the Smith & Wesson.
