Been a while since I last used, but IIRC Rabbit is much more featureful than Redis, and has built-in much of what you'd get from Redis + Sidekiq. Their concepts[1] docs provides a good overview. This may be too broad a stroke but what I liked best about it was we used it for our centralized pub sub system, and although we had services in multiple languages / frameworks, they connected to each other through Rabbit, which saved us from having to setup a bunch of different / incompatible job processing systems. Like Redis its battle tested so you know what you are getting complexity / scale wise. At my current gig we use the typical Rails / Sidekiq setup and though it works fine I definitely find myself missing Rabbit. (But in my head Redis / Rabbit have only some overlap, and seeing both at the same company would seem totally normal)
