As with everything else, which is best depends on your priorities. My main concerns are cost and damping.
As far as I can figure out carbon costs significantly more than wood -- and dampens less?
Point taken about usefulness of wood as firewood in the snow however you also forget to mention than in case of a nuclear apocalypse the metal and carbon tripods would probably not fare much better than the wooden ones (though have not had opportunity to test this theory yet).
