The flip side: what happens when it collects hangar rash? Repairing aluminum

Exactly, which along with the health related issues associated with
building a composite aircraft is why any of us still work with aluminum.

I can't speak for other composite airplanes, but in building a
Tango 2 or Foxtrot 4, the whole construction process teaches you to
repair any hanger rash or major damage. In one case we had an
airplane damged that the insurance adjuster said to repair. He said
he would have scrapped it if it had it been aluminum. What does this
prove? Not much. One could throw corrosion into the discussion. If
one material was universally better than the other, the other would
disappear. Health issues? We haven't seen any.
