an interesting point, I must admit.
From what I'm seeing on local and national news, it looks like Charley will do more damage than Andrew simply because of the scope of the storm. Andrew was small compared to Charley and while it did incredible damage to the Homestead/Florida City/Naranja area, the vast destruction was pretty much kept to those areas.
Charley was larger, went through the state across heavily populated areas. So far the confirmed death toll is the same as the "official" Andrew toll from the actual storm.
