So if you don't have any problems with the performance nor you have specific requirements use broadcast.
If you have large OSPF broadcast network, and you have many IR (Inner Routers) maybe it is good idea to reduce amount of OSPF peers - then you can set network type to NBMA and then specify only necessary neighbors manually in the NBMA Neighbor menu.
Point-to-point network type will reduce amount of the traffic on the link if you have only 2 directly connected hosts on this network.
