Neither is really "better". I believe that S&W typically have a smoother trigger than most typical Rugers however, like in the case of the Ruger GP, they come pretty close to Smith. Otherwise they are both well made guns and each has their fans.
I'd suggest buying which ever feels best to you. No matter what you buy, you'll know that you just bought one of the best made guns on the market from a maker that stands behind their products.
