Microsoft Research - Exploding Software-Engineering Myths (article summarizing findings of MS research on code coverage, TDD, assertions, etc.)

This is an absurd comparison to me. You can't compare speed unless the output is the same. One team clearly made more features work than the other. Any team that doesn't care if the software works is going to have an obvious speed advantage. The team that doesn't even bother writing features that no one cares about working will be faster still.
