The advantage of wood over synthetic? Well, no one spends the evening ooohing and aaaahing over their synthetic stocks. Wood just looks better.
Advantages of synthetic over wood? Lots, but not with the factory molded plastic stocks (all they do is make the rifle cheaper to manufacture). To see the advantage of synthetic over wood, you have to get a laid-up fiberglass, fiberglass/Kevlar, or Kevlar/graphite composite stock. The injection-molded foam stocks like the B&C, HS Precision, and some of the mcMillans are almost as bad as the plastic ones on factory rifles.
