Objects on S3 are replicated on 3 AZs (datacenters) by default and I can't find any info on B2 if they also replicate the data on multiple DCs. That can definitely change the cost per GB for them if that's the case.

B2 has 99.999999% durability

  That's just 8 9s. S3 has 11 9s.

    Depends upon your client SLA then. You can also store the file twice on B2 for still less than the cost of S3 :)

      Will failures be correlated then?

      Then you should be comparing it to reduced redundancy S3, which is cheaper than regular S3.

  That’s nice in theory, but if B2 has a castrophic disaster in thier one data center, that durability goes to zero.
