I would use an `enum` with one instance as singleton if you need to implement an interface. Otherwise, I would use an `enum` with no instances and static methods as a Utility class. – Peter Lawrey Jun 17 '11 at 10:34

Static methods follow the "low coupling and high coherence"-rule more than singletons do. (As long as their implementations don't rely on static member variables.)

If the static methods solve the same problem as the singleton, then why complicate and write a singleton?
Otherwise, why choose something that solves the wrong problem?
