Question about dual homed between two sites traffic flow design

What is the best way approaching the dual homed between two sites. We have two WAN links to the same provided and both links are at 1Gbps. Routers A and B are in site 1 and router C and D are in site 2. A is connected to C and B is connected to D. Should I load balance the traffic between the two links or make the second link standby and the first link active?

It seems like using both at the same time seems to be the best for me, but why would someone deploy active/standby between two sites?
