Worth upgrading Voyager to Prodigy controller?

My former RV dealer installed a Tekonsha Voyager brake controller in my TV when I bought my last trailer (an RPod). I've been using it with my Elkmont as well, but have always found it "finicky" to set up.

Most folks I've seen on these RV boards rave about the Tekonsha Prodigy controllers. This leads me to two questions:

1. Is it worth upgrading to the Prodigy and why?
2. If I do upgrade the controller, do they share the same plug connector in the back of the controller, or will I need to get a new pigtail cable designed to fit the Prodigy and my Buick?

Thanks in advance for your help.
