NSOperationQueue can be more suitable for long-running operations that may need to be cancelled or have complex dependencies. It is possibles to cancel operations that have been enqueued in an NSOperationQueue (as far as the operations support it).
NSOperationQueue gives you a lot more control over how your operations are executed. You can define dependencies between individual operations.
