Wood stocks generally offer more stability, but swell and can change POA when exposed to significant amounts of moisture. Wood stocks look much better in my opinion as well. Wood stocks are heavier, but help to reduce felt recoil with extra heft. Synthetic/composite stocks do not swell, lighter, are usually flimsier and do not look as good. You can get very good accuracy out of either with the right set-up. I would take these things into consideration and pick which ever one turns your crank the fastest!
