Or store it in Amazon AND store another copy in Backblaze. This isn't necessarily an "either/or" question. Having two copies with two different vendors in two separate regions is probably more reliable than having two copies inside the same vendor. For example, if Amazon has a large outage that affects both your regions, you can still access the copy in Backblaze.

If you're going to pick two providers, use Backblaze and Google. Google's Nearline Storage is still more reliable (AWS only offers a 98% SLA on a monthly basis for S3 IA storage class) and cheaper (if I recall properly) than AWS' Intermediate Availability offering.
