OSPF or BGP for I-MPLS Connectivity

Hi Experts,
 
I have real time scenario, in which we are running OSPF for
Inter-office connecitivity across locations inside the country and we are
opting for I-MPLS connectivity to connect international office.
 
Service
Provider recommends us to go for MPLS over BGP instead of MPLS over OSPF. The
reason for this is due to backdoor links and the complexity with Sham-links.
 
Please let me know your opinion on whether to go for MPLS over BGP or MPLS
over OSPF.
 
Regards,
Vignesh
