Central and super dispatch. New to cars

Hi.

Some background:
I'm leasing on a guy who has previous experience and a full set up for car hauling. He's coming over to help take some of my typical flatbed work that needs another driver, but will still fill time and miles locally with his car setup. His previous carrier used central dispatch and super dispatch to manage the central loads that he dispatched to his drivers.

My question is, do you really need both? I once trialed central dispatch but didn't continue because the only board I need is truckstop. Now it'd be nice to fill the occasion gap with a car or two but now with this dude having a full setup for cars it makes sense to get that subscription again. Just not sure I need 'super dispatch'. The two apps seem redundant. Do you get more features from one or the other?

Currently my setup is ITS for loads and QBO for invoicing, sending copies of BOL/POD. Seems like super and central dispatch are all about cars, not sure if both are required or maybe just one?
