I'm vertically challenged, so I appreciate how easy it is to shorten the LOP with a wooden stocked rifle.
Stock material hasn't entered the equation for the rifles I've bought thus far, it's just not on the list of things I care about (which are normally fit, utility for the task at hand, and customer service). The only time I would care is if I was buying some super fancy heirloom, like a Blaser R8, then it would have to be wood all the way.
