These are complementary, not opposing, technologies.

DRBD = block-level disk replication (think 'RAID 1 over a network')

Corosync = Cluster membership, ordered messaging, etc.

Pacemaker = Cluster resource management. That is, what runs where on the
cluster depending on the current membership.

So the short answer to you question is; All three.

The long answer depends entirely on what you are trying to do.
