Coming back to this after I've flown F9 now.
In all honesty, other than the livery on the outside of the planes, some of the brands offered on-board, and Spirit's Big Front Seat, there is really nothing differentiating the experience/cabins on F9, NK, and G4. They are all perfectly reasonable for the cost & risks and really you'd only pick one over the other depending on the routes they fly/where you want to go.
Also as a side note, at least the night I flew F9 out of Denver, they only policed your free carry-on if it had wheels to make sure you paid for it, otherwise despite the ads around the terminal warning you about your backpack size they never made anyone thrown their non-wheeled bag into the sizers. There was a family traveling that argued over not paying to bring their stroller and over carry-on on board but seeing them later board I'm assuming they eventually paid up lol.
