10mm Comparison - S&W 610 vs Ruger GP100 Match Champion

The Smith & Wesson 610 versus the Ruger GP100 Match Champion. This Ruger revolver is only one of two from Ruger that is chambered in 10mm. The other Ruger is much smaller and I have never seen one in person. The Smith and Wesson revolver is more common in stores than the Ruger, but neither is as common as an M&P pistol or a Glock. Both of these six shooter wheelguns are on the larger size, so concealing them as your EDC will require a little more thought if you don't live in sunny & warm Florida, as we do. Which of these two would you choose?
