Wood. There are great practical arguments for synthetics in the field, but I'm not sold. All my longarms have wood. All but two of my handguns have wood (and I'm making wood grips for one). For me hunting is as much about being outdoors and escaping from the daily grind as it is about getting food on the hoof|wing|foot. I pretend I live in earlier times, sitting out in my leather boots, wool shirt, knit cap and wood handled knife. You could call me a 1930's reenactor
A wooden stock is part of this. All the preseason rituals I would miss otherwise. Listening to the radio while steaming out dents. Rubbing with linseed oil every night, returning to my copy of 100 Years of Field and Stream(highly recomended hardcover collection BTW) to reread favorites. Mink oiling my boots and leather sling. Tightening up the snowshoes and working up a new load.
Stripping the wood off my guns would strip away the giddy pleasure I get from maintaining once living materials.
On the other hand, I could be a little silly upstairs. If the above doesn't apply to you, synthetic is likely just fine
