Aslask, urban grunge is too monotonic and i hate the head. I'd prefer nox demon set.
//Edit: although i do like the overall style of urban grunge. It would just need more colors (which also means more details).
//Edit2: A few pictures of texture sets that i like. Just thought this might give you an idea of what i like. The pics are taken from the sexyness competition or something.
You don't need to be scared that somebody is paricipating, everybody has their own style and the more to choose from the better. And the more interesting the set is the better too : D
