I have simple single node deployment and I was floored how easy it was to set up with Celery. Really surprised. I was kicking myself for not using it sooner.
Granted I don't know all the intricacies of RabbitMQ and this was just one step beyond os.popen, but it was painless, like half an hour painless to set up and it has worked really well.
*edit: reading some of the other posts now I'm waiting for the other shoe to drop. but so far it's worked wonderfully.
I also got my first queue set up and running within a reasonable period of time with celery. I have no idea of the internals of RabbitMQ and took longer with celery really (back on python 2.7) but that system has been in prod for 6 years now without really needing any maintenance
