Of course not one is the full-check, thus you'll have to combine a 
couple of them or write your own check.

I (well the script ;) also check the delegations from the root down and 
verify that all the nameservers in that tree think that they are the 
same SOA-wise and delegation-wise. You'll be astonished how often things 
break up in the tree that can cause rather odd and not easily found 
failures otherwise.
