Not really worse or better in practice.  The semantics are slightly different for the two cases, but the end result is the same.  In the revocation case, you have sig1+revoke1+sig2, so the end result is to use sig2.  In the superseding case, you have sig1+sig2, and the end result is also to use sig2.
