Unicast vs. Multicast

I understand, to quote wedge’s document…
“In unicast mode, the NLB network adapter is automatically assigned a new MAC address, and the original, hard-wired MAC address is disabled.”
“In multicast mode, the original, hard-wired MAC address of the NLB network adapter on each cluster node is preserved.”
Does anyone have a good resource on when to use one versus the other? I understand that your router must support Multicast MAC Addresses to do multicast. The MS Press Book has a chart on 7-18 listing the advantages and disadvantages when you have 1 or more network adapters with each configuration, but numbers of NIC’s aside, is there certain apps/environments/situations or anything that would lead a person to choose one versus the other?
*Update*
I did find in another thread dyna's suggesting
Selecting the Unicast or Multicast Method of Distributing Incoming Requests
