If both of them are a quality stock.. the composite is more weather proof probably and lighter. I have laminate stocks. They do make the rifle more heavy. But I have them well waxed and never had a problem in the rain and snow with them. Also they are a solid feeling rifle, absorb recoil real well, and are beautiful to look at. If I had the choice, and they were both high end stocks, I would probably take the composite stock though. But if all I could find was the laminate.. I would not overlook it for that reason.
