Wood is beautiful; fake wood is awful. Why? I guess it is because I don't like when materials pretend to be something they are not. Plastic! There is also a practical aspect to it: fake stuff often get worn and start showing their "other nature" - Whereas wood age gracefully.
I like surfaces that age gracefully. Like weathered wood, weathered steel/iron/copper, worn hide, etc. Just think of the difference between flaking paint and greyed weathering (is that a word?)
