I'm a little confused as to which one I should use. I think either will work, but is one better or more appropriate than the other?
If you need to send/receive messages to/from AMQP message queues, use carrot.
If you want to run scheduled tasks on a number of machines, use celery.
If you're making soup, use both ;-)
