Comment (by nickm):

 Oh, the above didn't rank AES256 vs AES128.  I claim that the weaknesses
 in the AES256 key schedule don't matter in practice, so let's prefer
 AES256.  Though rational people might decide that we don't need so many
 rounds, and a 256 bit key doesn't help.  I think that the key length is
 less important than any of the other issues.

 I've written a python program to do the sorting for me, since there's a
 bad track record for building these things by hand (#11498); attaching it
 here.
