Leatherman Arc or Obsidian?

Hey guys I have a dilemma. I can either order the Arc or get an Arc Obsidian (new) for about $270 in a local shop about 3 hours away from me. I will use the multi-tool, not a collector item. Both colors are cool, worried the black (obsidian) will wear off and get scratched up? Not sure. Which would you get?
