My experience with the either go as far as my ownership of a 6" Ruger GP100 and a stainless example of the 686 I once held in court during jury duty that was used in the commission of a crime. The Ruger seems beefier to me, but I'm not sure how much that matters to you. Both should handle any work just fine. The Ruger action on mine is pretty darn good (for a revolver, I'm more of a single action pistol guy) with a wonderfully smooth DA pull through-out and a glass rod on the SA end. It still punches my ticket with Magnum loads but shooting anything in .38 is much akin to a .22. Ruger revolvers are prized here in America so buy with confidence.
