Depends. Juice Defender extends my battery life by as much as 6-8hrs on regular usage. But that's because I have everything on auto-sync, so JD turning off connections for a time and rechecking just after a certain period does save battery more than letting the phone stay online all the time.
But then again, battery saving apps work only on certain situations. If you aren't like me who leaves packet data on all the time, they won't be of any help at all.
