I forgot one more, stubzones are only better than delegations because they mantain the related NS refreshed automatically, so you don't need to manually add new DNS servers to the delegation when they are added to that zone.

2 things:
Stubs don't replace the delegations.
Stubs CAN be used in place of a Delegation for
almost* identical results (although I personally don't
do this.)
*There are subtle differences in the cases of updated
DNS server addresses (and adding/removing DNS
servers) but these have little practical effect in most
small networks.
and
Stubs aren't the same has the Secondary zones.
No, they most definitely are not "the same" (since if
they were the same they would BE "secondary zones")
but they are best thought of as "secondaries without
most of the records."
Stubs are LIKE Secondary Zones in that they have the
SOA, NS, and address records for those DNS servers
and thus can be used to effectively find the authoritative
servers which can provide the "rest of the zone", BUT
are different in that they do not have the (vast majority)
of ordinary records held by a Primary or Secondary
zone server
The purpose of Stubs (as opposed to just using a Secondary)
is LARGELY for "giant zones" in which the admin would
like to use a Secondary but prefers to avoid transferring
entire zone, especially across slow WAN lines -- in such
giant zones it is probably that most requests will be for a
very small number (up to a few dozen) records, e.g., those
needed to resolve DCs and perhaps critical servers such
as file, print, or email servers while technically allowing
for any record to be resolved if that ever becomes necessary.
