If the Weatherby stock is of Bell and Carlson production, than that is kind of your answer as to which is better made. Of course, the price difference is reflective of that as well.

Weatherby's design, vs that of Remington is sort of apples oranges, because they are so different... but we are still talking about fruit here, and they are designed for the same purpose, but to different ends. As written, Weatherby designed his to direct recoil away from the face. More than a few shooters have been "scoped" by a Weatherby magnum. I think they are very comfortable to shoulder and put the shooter in a good position. My opinion, all depends on who is holding the rifle.

The Remington design is sort of a hodge-podge of several designs. Its part Monte Carlo, part straight, part German-esque. Straight stocks tend to help "manage" recoil the best, because they spread it out evenly. Recoil is more straight back, but it still doesn't tend to hit the face as bad as a standard monte Carlo, which in my opinion are some of the most evil. The cheek rest tends to seem to want to push the rifle away from the shooters face a bit. All depends on the rifle and the shooter as always.
