CISSP is a management level certification (1 mile wide, 1 inch deep).
CISSP is a lot more known, higher salary ranges than most other ITSec certificates.
When I did mine I did it as part of a IT security group of certificates, I took about 6 months, but it was part time (evenings/weekends), and I did a few in that time frame.
Since curriculum overlaps a lot I figured I would take 4 certifications with little extra effort.
