It's not; case is better.  cond is more general and, if anything, case will be more efficient.  In a typed language, case would also be safer.  (There are other situations, though, where you would want to use cond to perform a case-like operation.  If the scrutinee is an abstract type, for example, you might not be able to use case because case uses the language's built-in notion of equality.)
