I actually trust Docker Hub more compared to a private registry setup... had so many hard to debug EOF errors, registry container crashes, etc. But the Docker Hub is also a single point of failure, so now I'm considering just having our CI service dump (docker save) the container build to a tarfile and send it to S3, then having the destination host download it and run docker load. Docker's handling of layers is excruciatingly slow, anyway.
