I like them both and hove owned both. For shooting mostly .357's go with the Ruger. For .38's or .38 +P's go with the Smith. The Ruger is definitely a heavier revolver if weight is a consideration.
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” ― Samuel Adams
