I think iSCSI is easier to implement and is certainly fast, but I'm unclear about the number of iSCSI clients that can access a volume (iSCSI target) at the same time. So, I use it with only one client at a time.
iSCSI does allow multiple initiators to access a target simultaneously. Of course, the initiator's OS needs to handle the access properly via cluster-aware filesystem (VMFS, GFS2, etc) or locking mechanisms to avoid data corruption. Additionally, the target implementation may require support for certain SCSI reservation protocols to handle certain clustering implementations.
