* most idiomatic
* clearest in terms of showing intent
* potentially fastest
* hardest to screw up (unlike concatenating file names into a
   'system' call)
* has at least a snowball's chance of persisting metadata associated
   with the file (even if shutil doesn't now, it could theoretically
   change)
* portable

There's basically nothing NOT to like about shutil, and at least one 
significant problems with all the other suggestions.
