The SpaceX design is probably the less risky one. They are already flying a version of Dragon which is very similar, and will have many more flights of it by the time of the first crewed flights. The differences between the crew and cargo versions are important, but the CST-100, as a basically clean-sheet design, will have far less relevant flight heritage than Dragon.
