I see the cultural and historical differences between BSD distributions and Linux distributions as causes, and the technological differences as an effect. When measured according to some key qualities identified by Brooks [1], I would give the BSD's a better score than the Linux's: - Programming Systems Product - Conceptual Integrity In a commercial environment, the decision should be based upon total cost of ownership (TCO). Licensing may be a pass/fail criterion for options to consider, depending upon application (e.g. embedded). You should consider more than two FOSS alternatives, and you should include the hardware/ virtualization/ cloud dimension. Your question is one that could challenge a CIO. A thorough answer backed by objective data will require effort and expense.
