You are asking the wrong question. The best OS is the OS you (and/or the customer) knows and can administer competently. The real performance differences between unices are so small as to be ignorable in this context. The context switching bug is not OS-dependent, but varys in severity across machine architectures (I understand it to be mostly P4/Athlon related, but don't take my word for it).
