Extra $$ compared to what? If you have already bought EE - as others have said - then I would definitely go with DG. If you are considering buying EE - "just for" DataGuard *and just to provide a standby database* then I'm on record as saying it probably isn't worth it. Manual standby works just as well as it ever did.

Where DataGuard (9i+) scores is in the following areas.

1. Ease of administration.
2. Supportability (try talking to a support analyst about manual standby its harder than you might expect).
3. Flexibility. Try doing 5 different standby locations manually.

It also ought to score in the area of logical standby - but I haven't used that and in a survey of about 200 or so people at a SIG at which I was presenting i could only find one user of Logical Standby.
