I can't speak for the others but I've been hunting with the Ruger GSR for years. I have taken many deer with it. Very accurate with 165 Hornady SP's and Varget. My complaints are that it is heavy, and it just doesn't carry like a traditional bolt action. If you're not deer hunting with it that may not matter to you. Oh, and I mounted my scope over the receiver with the ruger rings and not in the scout configuration.
