I would say use loopbacks whenever you need redundancy or when going to a
neighbor over multiple load balanced interfaces, the loopback will never go
down and would be perfect for this. If you have only one connection to a bgp
neighbor over one interface I don't think there are any benefits to putting
your bgp session on the loopbacks.If the interface goes down your bgp
session will go down regardless if you were using loopbacks or not.
